Question

of sound stops as soon as the vibration of the source stops.

• A. Production
• B. Propagation
• C. Hearing

Answer 1

The correct option is A Production

Sound is produced due to vibration of the source of sound. Hence, as soon as vibration stops, production of stops also stops. However, propagation of sound continues unless it dies out due to some reason. Hearing does not stop immediately after the vibration stops. There is a small difference of time between the stopping of vibration and the stopping of hearing of sound.
