Detailed Solution

A person is listening a tone of

500 Hz

from the source of sound. The time interval of the sound waves is

0.002 s

.
Given,
Frequency of sound wave,

v = 500 Hz

Distance from source,

d = 450 m

It is known that “Time period is the reciprocal of frequency or frequency can be defined as the number of cycles completed per second.” If

T

is the time period and

v

is the frequency, then the relation is given by

T = \frac{1}{v}

On substituting the values, we get

\Rightarrow T = \frac{1}{500}

\Rightarrow T = 0.002 s

Hence, the time interval is

0.002 s

.
