Question

A wave produces 50 crests and 50 troughs in 0.05s . Find its frequency.​

Answer 1

Answer:

10000 Hz

Explanation:

One complete cycle consists of one crest and one trough.

The given source produces 50 crests and 50 troughs, hence it produces 50 wave cycles in the given interval 0.05 seconds.

Therefore, number of wave cycles produced in 1 second = (50/0.05)*1 = 10000

We know that the number of wave cycles produced in one second is equal to the frequency.

hence, it's frequency is 10000 Hz.
