Question

A boy heard a sound of frequency 100 Hz at a distance of 500 m from the source of sound. What is the time period of oscillating particles of the medium? plsfast

Answer 1

Given:
frequency=n=100Hz
time period=T=?
we know that
T=1/n
⇒1/100⇒0.01sec

Answer 2

Answer:

Time period, T = 0.01 seconds

Explanation:

It is given that,

Frequency of the sound, f = 100 Hz

Distance between the sound source and the boy, d = 500 m

Let T is the time period of oscillating particles of the medium. We know that the relationship between the time period and the frequency is given by :

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

$T=\dfrac{1}{100\ Hz}$

T = 0.01 seconds

So, the time period of oscillating particles of the medium is 0.01 seconds. Hence, this is the required solution.
