Chapter 14, Problem 8STP

To determine

To Choose: The correct option.

Answer to Problem 8STP

Option C

Explanation of Solution

Introduction:

Standing is a wave that oscillates in time but its peak amplitude profile is stable in space.

They are formed as a result of superposition of two travelling waves which have same frequency. They travel in opposite directions. By using a travelling wave and its reflection, it can be achieved and ensures that the frequency is the same.

Standing wave is aresultant of combination of two waves which are moving in opposite directions and each of them has similar amplitude and frequency.

The standing wave can be described by using identical waves, moving in opposite direction and same medium.

Conclusion:

Thus, option C is the correct option.
