Video answer: Wave speed on a string - tension force, intensity, power . ## Top best answers to the question «How does velocity work in a wave»

Wave velocity in common usage refers to speed, although, properly, velocity implies both speed and direction. The velocity of a wave is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity.

FAQ

Those who are looking for an answer to the question «How does velocity work in a wave?» often ask the following questions:

### 👋 Does wave type affect wave velocity?

• 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 wave type effect wave velocity?

Both Wave A and Wave B travel at the same speed. The speed of a wave is only altered by alterations in the properties of the medium through which it travels… The wavelength of a wave does not affect the speed at which the wave travels. Both Wave C and Wave D travel at the same speed.

### 👋 Does amplitude affect wave velocity?

• For all electromagnetic waves (in a vacuum) the velocity = c, the speed of light. Accordingly, how does changing the amplitude of a wave affect the wavelength and the frequency? The amplitude of a wave does not affect the speed at which the wave travels. The wavelength of a wave does not affect the speed at which the wave travels.

Who discovered wave velocity?

#### How does the velocity of a wave change with time?

• In wave motion, the perturbations travel through the medium due to repeated periodic oscillations of the particles. The velocity of the wave will be different from the velocity of the particles with which they vibrate about their mean positions. The wave velocity will always be constant but the particle velocity will be changing with time periods.
How are particle velocity and progressive wave velocity related?
• In a plane progressive harmonic wave, the constituent particles in the medium oscillate simple harmonically about their equilibrium positions. When a particle is in motion, the rate of change of displacement at any instant of time is defined as velocity of the particle at that instant of time. This is known as particle velocity.
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 fluid affect wave velocity and attenuation?
• The fluid effects on wave velocity and attenuation depend on the frequency range. At low frequencies, the fluid has enough time to achieve pressure equilibration (relaxed regime) and Gassmann modulus properly describes the saturated bulk modulus.
How does the velocity of a wave change?
• Velocity of a wave = frequency x Wavelength. So by change in Amplitude there is no change in velocity , frequency or the wavelength but Energy or Intesity varies as the square of Amplitude so by making amplitude double energy will become 4 times.

### Video answer: V = λf, velocity of a wave, graphs What does the velocity of a wave describe?
• Wave velocity is the speed the wave propagates in a medium . Wave velocity is a property of the medium. This can be described by the term impedance. Impedance is the resistance of the medium to the propagation of the wave.
What does the velocity of a wave measure?

### Video answer: Calculate the speed of a wave - worked example - gcse Why does arterial stiffness increase pulse wave velocity?
• Arterial stiffness caused by medial calcification and loss of elasticity (i.e. aging) is the most important factor contributing to an increase in PWV. Pulse wave velocity (PWV is an effective and highly reproducible measure for evaluating vascular endothelial dysfunction (i.e. the elasticity of the artery) and arterial stiffness.
Why does p wave velocity increase with depth?

As the pressure increases (increasing depth of travel) the quantity (B+G) increases faster than Density. Therefore, with increasing depth we expect the velocity of the P wave to increase.

Why does pulse wave velocity increases with age?

With age, or due to changes in the arterial wall, these vessels become stiffer and the speed at which the pressure wave moves through the system is increased. In addition, there are reflected pressure waves that move back towards the heart at the end of the systolic period.

### Video answer: Velocity, acceleration and distance traveled for points on wave Why does seismic wave velocity increase with depth?

Seismic velocities tend to gradually increase with depth in the mantle due to the increasing pressure, and therefore density, with depth. However, seismic waves recorded at distances corresponding to depths of around 100 km to 250 km arrive later than expected indicating a zone of low seismic wave velocity.

Why does the velocity of a wave change?
• The velocity changes because the electric field drags charges back and forth, which slows it down. There is no simple formula in terms of density, because other properties are also important, like dielectric constant. The index of refraction is an empirical ratio of the speed of light in vacuum to that in the medium.
How to calculate wave velocity?
• Ans: The velocity of the wave can be calculated by knowing the wavelength of the wave and the frequency of the wave. Mathematically it is given by, ⇒ v = λv
Is pulse wave velocity accurate?

With the same imaging parameters, pulse-wave velocity can be measured for 1.4 cm of vessel with 10% accuracy.

What controls seismic wave velocity?

The manner and speed of seismic waves travel through material is controlled by their elastic properties. E is the constant of proportionality called an elastic modulus. Units of elastic modulus are the same as pressure � i.e. MPa or GPa.

What is pulsedpulse wave velocity?
• Pulse Wave Velocity is the propagation speed of this wave along the arteries. Pulse Wave Velocity is usually measured between the carotid and the femoral artery using applanation tonometry. However, this technique requires an advanced equipment and a well-trained operator.
What is wave speed velocity?

Wave velocity, distance traversed by a periodic, or cyclic, motion per unit time (in any direction). Wave velocity in common usage refers to speed, although, properly, velocity implies both speed and direction… All sound waves travel with the same speed in air regardless of their frequency.

What is wave velocity formula?

The wave velocity formula says it is the product of wavelength and the frequency of the wave. I.e., Wave velocity (v) mathematically is given by, ⇒ v = wk.

### Video answer: What is velocity? | physics | don't memorise What is wave velocity meaning?
• The wave velocity definition is given as the velocity associated with the disturbance propagating in the given medium or in other words, wave velocity is the distance travelled by period motion per unit time. The wave velocity depends upon the nature of the medium used.
Which wave has highest velocity?

Primary Waves (or P-Waves) - These are compressional waves, also known as longitudinal waves and are the first seismic waves to arrive at a location on the Earth. This type of wave has the highest velocity for traveling through Earth materials.

How do you find the wave velocity with velocity factor?
• If we know the velocity factor, the wave velocity is Example: Calculate the wave velocity in a coaxial cable with velocity factor 0.66. The wave travels slower in the coaxial material. To obtain the wave velocity, we multiply the speed of light by the velocity factor.
