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 ?

Text Solution

AI Generated Solution

To find the time interval between successive compressions from the sound source, we need to determine the time period of the sound wave. The time period is the time taken for one complete cycle of the wave, which includes one compression and one rarefaction. ### Step-by-Step Solution: 1. **Identify the Frequency**: The frequency of the sound wave is given as \( f = 500 \, \text{Hz} \). 2. **Understand the Relationship Between Frequency and Time Period**: The time period \( T \) is related to frequency \( f \) by the formula: \[ ...
