Question

The frequency of a wave travelling at a speed of 500 ms- 1is 25 Hz. Its time period will be ______.

Answer 1

Time period = 1/ frequency = 1 /25 = 0.04 s

Answer 2

Answer:

We know, time period is equal to 1/frequency.

Given, speed of the wave = 500 m/s, frequency of the wave is equal to 25 Hz.

Hence, time period = 1/25 = 0.04 s.

Thus, the wave of frequency 25 Hz would travel at a speed of 500 m/s in 0.04 s.
