Question

If time period of a wave is 0.004s, find the frequency of the wave .

Answer 1

ANSWER ♡

Data = T = 0.004 s , v = ?

$v = \frac{1}{T}=\frac{1}{0.004s}=\frac{1000}{4} Hz =250 \:Hz$

The frequency of the wave = 250 Hz.

Answer 2

Question:

If the time period of a wave is 0.004 s find the frequency of the wave.

Answer:

250 Hz

Explanation:

We know,

◙ Frequency is the reciprocal of time period.

$\sf{F=\dfrac{1}{T} }$

Given,

T = 0.004 secs

Putting the values :-

$\sf{F=\dfrac{1}{0.004} }\\\\\boxed{\sf{\hookrightarrow F=250\ Hz }}$

Hence, the frequency of the wave is 250 Hz.
