Question

Problem 8

Answer 1

Given information

A wave's speed is determined by

 

 

Here,

is the Frequency'

is the wavelength

The wavelength is exactly related to the velocity, as can be shown.

 

The frequency of the sound does not vary in this case.

 

However, sound travels at a slower speed in the air.

Step-by-step explanation

Step 2.

The product of the wavelength and frequency determines the speed of sound in the string, hence sound waves in the air have a shorter wavelength than waves on the string.
