Chapter 9, Problem 35R

To determine

The correct option.

Answer to Problem 35R

The correct option is A.

Explanation of Solution

Introduction:

Amplitude is the maximum extent of vibration from the equilibrium point.

The energy which is transmitted by a wave is directly proportional to the square of amplitude.

Wave energy is generated by the disturbance from the wave.

Mathematically it can be expressed as,

  $\text{wave}\text{energy}=k{A}^2$

Here, $k$ is constant of proportionality and $A$ is amplitude.

Frequency remains unchanged with change in amplitude and wave speed. so option A and C are incorrect.

Refraction is not related to amplitude hence option D is incorrect.

So it is clear that if amplitude of wave changes disturbance from the also changes.

Conclusion:

Therefore, the correct option is A.
