Question

An object is vibrating at 50 hertz. What is its time period?

Options

• 0.02 s

• 2 s

• 0.2 s

• 20.0 s

Answer 1

0.02 s

Explanation:

We know that

Frequency (f) = 1/Time period

Time period = 1/Frequency

Given parameter

An object is vibrating at 50 hertz.

50 = `1/"T"`

`"T" = 1/50`

T = 0.02 s

Its time period will be 0.02 sec.
