If a bell is ringing inside a bell jar, we can no longer hear it when the air is evacuated, but we can still see it. What differences in the properties of sound and light does this indicate?
Step 1 of 1 The main reason is light waves propagates in air / vacuum with high speed( 3× 10 m/s )8 but sound waves cannot propagate in vacuum. Material medium is required to travel sound waves from one place to another place. When the air is evacuated we can't hear sound of bell obviously due to absence of material medium.
