Answer 1

Answer:

When a bell rings , sound is produced , but as the jar is evacuated so it has no medium for sound waves to travel , therefore no sound will be heard . Because sound waves are mechanical longitudinal waves and mechanical waves require a medium , having the properties of inertia and elasticity , and in vacuum these properties are absent hence sound doesn't travel in vacuum .
