Video answer: What is time? a definition of time based on the frequency of energy waves.

## Top best answers to the question «How does time change with wave frequency»

Because, the speed of the sound wave changes when the frequency is changed. Because, loudness of the sound wave takes time to adjust after a change in frequency. Because it takes time for sound to reach the listener, so the listener perceives the new frequency of sound wave after a delay.
• The time interval for 1° of phase is inversely proportional to the frequency. If the frequency of a signal is given by f, then the time t deg (in seconds) corresponding to 1° of phase is tdeg = 1 / (360f) = T / 360. Therefore, a 1° phase shift on a 5 MHz signal corresponds to a time shift of 555 picoseconds.
• Since wave frequency is the number of waves per second, and the period is essentially the number of seconds per wave, the relationship between frequency and period is f = 1 T 13.1 or T = 1 f, 13.2 just as in the case of harmonic motion of an object. We can see from this relationship that a higher frequency means a shorter period.

FAQ

Those who are looking for an answer to the question «How does time change with wave frequency?» often ask the following questions:

### 👋 Does wave frequency change with distance?

Distance will not change the frequency. When speaking of sounds that are a mixture of frequencies, such voice or music, lower frequency sounds will remain audible at greater distances than high frequency sounds.

### 👋 Does the frequency of a wave change with different mediums?

• It surely is a sensible question. Actually the frequency of a wave remains same when it moves from one medium to another. But it's wavelength and speed do change with refractive index, which is different for different media.

### 👋 Does light wave frequency change between media?

When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn.

Does the frequency of a wave change during refraction?

#### Wave speed, frequency and wavelength in refraction

Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes… Part of the wave travels faster for longer causing the wave to turn. How does frequency change the sound of a wave?
• Likewise, the frequency of a sound wave is measured by how many air vibrations reach our eardrums every second. Frequency is what makes one note different from another, in a very simple way: higher frequency means higher pitch. Booming bass notes have very low frequencies, while piercing treble notes have very high frequencies.
How does the frequency of a carrier wave change?
• Frequency of an input signal can also be changed. If this input signal is added to the pure carrier wave, it will thereby change the frequency of the carrier wave. In that way, users can use changes of frequency to carry speech information.
How does the frequency of a sound wave change?
• All that said, there are physical processes that can change the frequency of sound, or at least introduce some new frequencies. For example, there are materials that can interact with a sound wave and change its shape, distorting it so that an originally pure single-frequency sound wave acquires overtones at higher frequencies.
How does the frequency of an electromagnetic wave change?
• The frequency of an electromagnetic wave increases as wavelength decreases. As wavelength decreases (and frequency increases) energy increases.

### Video answer: The wave equation - why speed = frequency x wavelength

Why does wave length and frequency change for waves?

When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same.

How do wave packets change shape with time?
• The wave packet does not change shape with time. These waves are nondispersive. Click to download the MPEG movie Case A. Case B is identical to Case A but the waves propagate to the left. To view Case B run Case A backwards in time.

### Video answer: Sound: wavelength, frequency and amplitude.

Does a wave with low frequency carries less energy than a wave with a high frequency?

Yes. For electromagnetic radiation, the formula is E = hv, where E is energy in Joules, h is Planck's constant, 6.626 Ã— 10-34 m2 kg/s and v is frequency. So the energy of a wave is directly proportional to the frequency. The greater the frequency, the greater the energy.

How does the frequency of sound change with distance?
• The frequency of sound doesn't decrease with distance, but it does derease with increasing distance, meaing it does go through the doppler shift, same as light.
Does frequency of a light wave change in different mediums?

When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases… The wave is slower but the wavelength is shorter meaning frequency remains the same.

### Video answer: Duty cycle, pulse width & frequency - rectangular and square waves

When does the wavelength and frequency of a wave change?
• Wavelength and frequency are intrinsic characteristics of a wave. In almost all cases, they do not change during reflection. They may change if the medium is nonlinear and/or moving.
A wave with high frequency?

The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths.

Why does square wave frequency affect triangle wave frequency?
• The higher the square wave frequency, the lower the resulting triangle wave if you use "normal" integration circuitry. If you want to address this issue you could "filter" the square wave and use a peak measurment circuit to produce a "control" voltage that rises linearly as the squarewave frequency increases.
Does wave velocity stay constant with increasing frequency?

If wavelength changes due to a change in the medium through which it travels, that affects only the wavelength, not the frequency. With frequency remaining constant and the wavelength increasing, then velocity increases. With frequency remaining constant and wavelength decreasing, velocity decreases.

How does the frequency of a wave change as its wave length changes?

The frequency of a wave change as its wave length changes by a longer wave length and has a lower ferquency.

Does wave frequency affect wave speed?
• The data convincingly show that wave frequency does not affect wave speed. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant. The last three trials involved the same procedure with a different rope tension.
Does the speed of a wave change when the frequency or?
• In most cases yes, the speed of a wave does change depending on the frequency. This is not always the case. For example, the speed of light in vacuum is constant regardless of the frequency.
What does it mean to change the frequency of a wave?
• This is called amplitude modulation or AM. Frequency of an input signal can also be changed. If this input signal is added to the pure carrier wave, it will thereby change the frequency of the carrier wave. In that way, users can use changes of frequency to carry speech information. This is called frequency modulation or FM.

Can you change the frequency of em wave?

Once the wave has left the source that generated it, the frequency can't be changed.If you happen to be moving toward or away from the source at a high enoughspeed, then the frequency of the radiation may appear to you to be changed.But it's not.

What can change the frequency of a wave?

frequency remains constant when light passes through different mediums . only speed changes and due to it , wavelength also changes. one way of changing the frequency is by Doppler effect, where the apparent frequency changes due to motion of the source ,observer or both of them.

How does frequency of a wave compare with the frequency of the source?

the wave length is smaller and more compressed at the source

Does amplitude affect wave frequency?

Not at all.

Does frequency affect wave energy?
• Higher the frequency of the wave, more is the energy carried by it. A wave with higher frequency would have more energy, and thus more energy will be transferred to the electrons. Lol so it's another question where we're not supposed to ask why?
Does frequency affect wave speed?

The data convincingly show that wave frequency does not affect wave speed. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant.
