Question

What is the frequency of wave whose time period is 0.05 sec?

Answer 1

A time period is the overall time that is required for the vibration to complete one cycle during a given point in time.

With the increase in the time period, the frequency of the wave decreases. 

When the time period of a wave is 0.05 seconds its frequency = 1/the given time period, given time period = 0.05 sec thus f = 1/0.05 = 20 Hz

Answer 2

Explanation:

frequency = 1/time period

1/0.05

1/5×100

20 hz
