Question

Which of the following statements is correct regarding the wave A and wave B? (Amplitude is same)

• A. B has comparatively low frequency.
• B. The time period of A is comparatively more than B.
• C. B has comparatively high frequency.
• D. Both the waves will have same shrillness.

Answer 1

The correct option is C B has comparatively high frequency.

As the number of oscillations of A is more than B for a particular amount of time, we can say, A has comparatively more frequency than B. Also the time period of A is less than B. We can check it by the relation $f=\frac{1}{T}$.
