Answer:

C. Is correct

Explanation:

For a sound wave it depends on how much compression the loud speaker or musical instrument creates.  In other words, it depends on the energy the source put into the wave. It does not depend on frequency, wavelength, or velocity.

The correct answer is option 3 as it explains Wave speed depends on the amplitude of the wave.

In the case of sound waves, it depends on how much compression the speaker or instrument produces. In other words, it depends on the energy the source puts into the wave. It does not depend on frequency, wavelength, or speed.

Wave amplitude does not affect the speed at which the wave propagates. Wave velocity depends on both wavelength and wave frequency. Most wave velocities depend on the medium or substance through which the wave passes. Sound waves travel faster in air and water than in solids and gases.

What is wave amplitude?

Amplitude, in physics, is the maximum displacement or distance that a vibrating object or point on a  wave has moved, measured from an equilibrium position. This corresponds to half the length of the vibration path.

Hence it concludes that Wave speed depends on the amplitude of the wave.
