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. … Longitudinal waves
What determines the velocity of a wave?
Multiplying the wave’s frequency by its wavelength, which is its physical length
, yields the velocity of the wave. The relationship can be expressed as velocity equals frequency times wavelength.
What does the velocity of sound depends on?
2 The velocity of sound. Sound velocity (c) depends upon
the medium
and also, in the case of gases, upon the temperature (but not, within normal limits, on pressure).
Which of the following does the speed of wave depend?
Yes, the speed of propagation depends only on
the frequency of the wave
. Yes, the speed of propagation depends upon the wavelength of the wave, and wavelength changes as the frequency changes.
Does velocity of a wave depend on amplitude?
The amplitude of a wave does not affect the speed at
which the wave travels. 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.
What is the relationship between velocity and amplitude?
The displacement amplitude is the maximum change in position. The
velocity amplitude is the maximum change in velocity
. The acceleration amplitude is the maximum change in acceleration.
Which waves has the highest velocity?
The correct answer is
Light
. The speed of light in the air is 3 × 10
8
m/s. The speed of light in a vacuum is 186,282 miles per second (299,792 kilometres per second). In theory, nothing can travel faster than light.
What is the velocity of a wave with a frequency of 10 Hz?
Velocity = Wavelength x Frequency
V = 5 x 10 → V= 50 meters per second
Solve using the wave velocity equation: (Show your equation set up and math work) 1- A wave has a Wavelength of 12 meters and a Frequency of 10 Hz.
What units are for velocity?
| Derived quantity Name Symbol | speed, velocity meter per second m/s | acceleration meter per second squared m/s 2 | wave number reciprocal meter m – 1 | mass density kilogram per cubic meter kg/m 3 |

What is wave velocity Class 9?
Wave velocity can be defined as
the distance travelled by a wave in one second
. It is also known as wave speed.
Does speed of sound depend on frequency?
Even though wave speed is calculated using the frequency and the wavelength, the wave speed is not dependent upon these quantities. … The speed of a sound wave depends on
the properties of the medium through which it moves
and the only way to change the speed is to change the properties of the medium.
How does speed of sound depends on density?
When the medium is dense, the molecules in the medium are closely packed which means that the sound travels faster. Therefore, the speed of sound
increases as the density of the medium increases
. The temperature of the medium and the sound waves are directly proportional to each other.
What is velocity of sound in vacuum?
The speed of sound in a vacuum is
zero meters per second
, as there are no particles present in the vacuum. Therefore the vacuum speed of sound waves in vacuum will be zero.
What is wave 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 the period wave?
Wave Period:
The time it takes for two successive crests (one wavelength) to pass a specified point
. The wave period is often referenced in seconds, e.g. one wave every 6 seconds.
What is wave height called?
As is shown on the figure, wave height is defined as the height of the wave from the wave top, called the
wave crest
to the bottom of the wave, called the wave trough. The wave length is defined as the horizontal distance between two successive crests or troughs.
