The period is the time taken by the wave to complete an oscillation. The frequency of the given sound is 500 Hz.
<h2>Period:</h2>
It is the time taken by the wave to complete an oscillation. The frequency is inversely proportional to the time:
Where,
- frequency
- period = 0.002 s
Put the value in the equation,
Therefore, the frequency of the given sound is 500 Hz.

Answer:
It will take about 1.32 seconds to travel to his location.
Explanation:
Considering the sound travels at 340 m/s, then if a person is at a distance of 450 m m from the bell, we can use the velocity formula to find the answer;
