Question

What is the time period of a 40 Hz wave?

Answer 1

Answer:

The formula for time is: T (period) = 1 / f (frequency). λ = c / f = wave speed c (m/s) / frequency f (Hz). The unit hertz (Hz) was once called cps = cycles per second.

Explanation:

Answer 2

The time period of the wave is 0.025 s.

Explanation:

The time period of the wave in terms of frequency is given by

$T=\frac{1}{f}$

Here, T is time and f is frequency.

Given, f = 40 Hz

Substitute the given values, we get

$T=\frac{1}{40Hz}$

T = 0.025 s.

Thus, the time period of the wave is 0.025 s.
