Chapter 9, Problem 4STP

To determine

To Choose: The correct option.

Answer to Problem 4STP

Option D

Explanation of Solution

Introduction:

The number of waves that passes a point in a certain time is called ‘Frequency’ of the wave..

Consecutive pair of a crest and a trough is called one cycle of wave or one wave and number of cycles of wave’s passes in a certain time is called frequency of the wave.Therefore, the option D is correct.

The length travelled by the wave in completing one cycle is called wavelength of the wave.Thus, the option A is incorrect.

The maximum displacement of medium particle from its mean position is called amplitude of the wave.Thus, the option B is incorrect.

The time taken by wave to complete one cycle is called period of wave.Thus, the option C is incorrect.

Conclusion:

Thus, the option D is correct.
