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

Given:

  • Frequency (\nu) = 500 \text{ Hz}

Concept: The time interval between successive compressions is equal to the Time Period (T).

Formula: T = \frac{1}{\text{Frequency}}

Calculation:

T = \frac{1}{500}
T = 0.002 \text{ s}

Answer:
The time interval between successive compressions is 0.002 s.
