If the amplitude of vibration is large, sound is feeble.
A person is standing at the seashore. An observer on the ship which is anchored in between a vertical cliff and the person on the shore fires a gun. The person on the shore hears two sounds, 2 seconds and 3 seconds after seeing the smoke of the fired gun. If the speed of sound in the air is 320 ms-1 then calculate:
1) the distance between the observer on the ship and the person on the shore.
2) the distance between the cliff and the observer on the ship.
The frequency is measured in second.
The quality of a sound depends on the amplitude of wave.
Explain the mechanism of the formation of a longitudinal wave when the source vibrates in the air.
