Question

the time period of a wave is 0.02 second.find its frequency.​

Answer 1

Answer:

Explanation:

Given ⇒

Time Period(T) = 0.02 seconds.

Now, Before Solving the Question, we must know what is frequency?

∴ Frequency is the number of vibrations made per seconds.

Using the Formula,

 Frequency (f) = 1/Time Period.

⇒ f = 1/T

∴ f = 1/0.02

∴ f = 50 Hz. (or f = 50 s⁻¹)

Hence, the Frequency will be 50 Hz.

Answer 2

Answer:

The frequency of a wave whose time-period is 0.02 s is 50 Hz.
