Question

Suppose a low-frequency sound source is placed to the right of a person, whose ears are approximately 13 cm apart, and the speed of sound generated is 340 m/s. How long (in s) is the interval between when the sound arrives at the right ear and the sound arrives at the left ear

Answer 1

The time taken by the sound is
`3.82* 10^(-4)\ s`

Step-by-step explanation:

We have,

A low-frequency sound source is placed to the right of a person, whose ears are approximately 13 cm apart, and the speed of sound generated is 340 m/s.

It is required to find the time taken by the sound when the sound arrives at the right ear and the sound arrives at the left ear. Let t is the time taken. It can be calculated as :

`v=(d)/(t)\\\\t=(d)/(v)\\\\t=(0.13)/(340)\\\\t=3.82* 10^(-4)\ s`

So, the time taken by the sound is
`3.82* 10^(-4)\ s`
