question_answer 10)

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:

Here, frequency of the source, time period of the tone,   The time period between successive compressions from the source is equal to the time period of the tone, i.e., (1/500) s and it has nothing to do with the distance (450 m) of the person from the source provided the sound wave reaches the person.
