Question

A person is listening to a tone of 500 Hz sitting at a distance of 450 m from the source of the sound. What is the time interval between successive compressions from the source?​

Answer 1

$\huge{\underline{\underline{\boxed{\sf{\purple{Answer ࿐}}}}}}$

The time interval between successive compressions from the source is equal to the time period and time period is reciprocal of the frequency. Therefore, it can be calculated as follows:

T= 1/F

T= 1/500

T = 0.002 s.

Answer 2

500Hz means 500 oscillations per second, so it's obvious what the taken time is for one oscillation it will be 1/500 second, so the time interval between two successive compressions is 1/500 second.
