A a person who is sitting at the distance of 400 m from the source of sound is listening to a sound is 600 heads find that time period between successive compression from the source person who is sitting at a distance of 400 m from a source of sound is listening to a sound 600 hertz find the time period between successive compression from the source

Answer 1

We know that

Frequency = 1/Time Period

OR

Time Period= 1/Frequency

Here, frequency= 400Hz

Therefore

Time period= 1/400= 0.0025seconds.
