Answer:
"It will be more than the speed of sound waves in air at 20*C and water at 20*C."
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.
[tex]Speed of sound = V = \sqrt{\frac{Elasticity}{Density} }[/tex]
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.
