A student performs an experiment using the setup as shown. The tin can is cut open from its bottom and a rubber sheet is stretched to cover it. A small mirror is glued to the rubber sheet. What would happen to the circular spot of light on the wall when the student speaks into the open end of the tin can?
The image shows reflection of sound by a wall What change would cause reverberation of the sound?
Assertion (A): Infrasonic waves are longitudinal waves of frequency greater than 20,000 Hz. Reason (R): The maximum frequency of audible sound waves is 20,000 Hz.
