Those who are looking for an answer to the question «Wave length of a wave is?» often ask the following questions:

### 👋 Formular of wave length?

Wavelength lambda is equated to the ratio of the speed of the wave to the frequency of the wave. So L = c / f Here L the wavelength, c the speed of the wave and f the frequency of the wave

### 👋 What is wave length?

Definition: Wavelength can be defined as **the distance between two successive crests or troughs of a wave**. It is measured in the direction of the wave.

is the distance between two vibrations or pulses of the wave..it is expressed by lamda λ and measured in m . it is equal to = v x t = v/f v= speed of wave t= period f= frequency

Do wave length remain constant?It depends on the type of wave you mean and the situation applied to. Water waves slow down when they reach shallow water and their wave-length shortens. This is why waves 'break', the back-side of the wave over-takes the slower lead-side. Light waves, when they encounter a polar molecule are absorbed and remitted at a shorter wave length. Electrons (wave-particle duality) change their wave-length when changing energy states.

- The frequency and
**wavelength**of a wave are related. When frequency increases more wave crests pass a fixed point each second. That means the wavelength shortens. So, as frequency increases, wavelength decreases.

- When frequency increases more wave crests pass a fixed point each second. That means the wavelength shortens. So, as frequency increases,
**wavelength decreases**. The opposite is also true—as frequency decreases, wavelength increases. Popular Trending

WAVELENGTHS OF VISIBLE LIGHT

All electromagnetic radiation **is light**, but we can only see a small portion of this radiation—the portion we call visible light… Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.

Wavelength can be calculated using the following formula: **wavelength = wave velocity/frequency**. Wavelength usually is expressed in units of meters. The symbol for wavelength is the Greek lambda λ, so λ = v/f.

That depends on its momentum.

~625-740 nm

.

The wavelength of a sinusoidal wave is the spatial period of a wave, that is the 'distance' over which the wave's shape repeats. Wavelength is commonly designated by the Greek letter lambda (?). Wave length is a measure that is used to determine different pitches and colors. Red has a longer wave length then blue and a higher pitch has a more compact wave length then a low pitch. It is basically a measurement of the visible and auditory stimulus around us.

#### Dictionary

- 1. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave: "a range of wavelengths"
- ▪ a wavelength as a distinctive feature of radio waves from a transmitter.
- 2. a person's ideas and way of thinking, especially as it affects their ability to communicate with others: "when we met we hit it off immediately—we're on the same wavelength"

Assuming you mean the wavelength: Radar can use electromagnetic waves of VERY different frequencies; see this section of "Radar" in Wikipedia: https://en.wikipedia.org/wiki/Radar#Frequency_bandsThe list also includes the corresponding wavelengths; or you can divide the speed of light by the frequency.

it can be illustrated by the Heisenberg's uncertainty principle,that says that,it's almost impossible to determine the exact velocity & position of a moving electron.

300 MHz: λ = about 3.278 feet.

Namely, if we know the frequency (which is the number of wave repetitions per second, often given in Hertz, or Hz) and the sound speed (which is the speed the wave travels in meters per sec), then we can find the wavelength using the **equation wavelength=speed/frequency**.

- To calculate the wavelength of a radio wave, you will be using the equation: Speed of a wave = wavelength X frequency. Since radio waves are electromagnetic waves and travel at 2.997 X 10^8 meters/second, then you will need to know the frequency of the radio wave.

The wavelength is equal to the speed divided by the frequency.

first we must ask our selves do these waves really exist?

# If you take a snapshot of a physical wave (such as an ocean wave) using a camera for example, you can then measure the distance from one peak to the next. The spacing is the wavelength. See the "mathematical description" section of the related link. When an an electromagnetic wave is discussed, the wavelength is equal to the quotient (speed of light / frequency). The formula applies to other waves too, just that the speed of light being replaced with the speed of the specific wave in question. For a traveling wave, see the "simple harmonic motion" illustration in the link -- the peak of the wave is moving at a finite speed to the right (i.e. wave speed). The wave frequency is how many times, at any spot in space (the center line, or the two boundaries of the "simple harmonic motion" illustration can be selected to do the counting), the wave peaks, troughs, and then peak again. Visible lights, X-rays, microwave, and gamma rays, all have a range of frequencies published in the literature.

Their wavelengths vary from 1 mm to 100000 km.

it depends on the size of the wave
