Sound: Elasticity, Density, and the Speed of Sound

The video explains how sound travels through different mediums, highlighting that sound travels fastest in solids due to their high elasticity. It also discusses how elasticity affects sound travel, with solids being more elastic than liquids and gases. Additionally, the video covers how density impacts sound speed within the same medium, using lead and aluminum as examples.

What role does density play in the speed of sound in solids?

Compare the speed of sound in lead and aluminum. What is the reason for the difference?
