Question

Based on the type of medium, what can you assume about the speed of sound in glass?

Question 10 options:

It will be more than the speed of sound waves in air at 20*C and water at 20*C


It will be less than the speed of sound waves in air at 20*C


It will be less than the speed of sound waves in air.


It will be between the speed of air at 20*C and water at 20*C.

Answer 1

"It will be more than the speed of sound waves in air at 20*C and water at 20*C."

Step-by-step explanation:

Speed of sound in a medium depends upon the density and elasticity of the medium.

If the elasticity of a medium is greater and the density of that medium is lower, sound will travel faster. Although density is also a factor but the major factor is Elasticity.

Hence, sound travel faster in solids than in liquids and even slower in gases due to elasticity difference.

`Speed of sound = V = \sqrt{(Elasticity)/(Density) }`

That is why the speed of sound in glass will be more than the speed of sound waves in air at 20*C and water at 20*C.
