The ratio of the amplitudes of two waves is 3 : 4. What is the ratio of their loudness?
A person standing between two vertical cliffs and 480 m from the nearest cliff shouts. He hears the first echo after 3s and the second echo 2s later. Calculate:
1)The speed of sound.
2) The distance of the other cliff from the person
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.
Explain the mechanism of the formation of a longitudinal wave when the source vibrates in the air.
