State one important property of waves used for echo depth sounding.
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.
What is longitudinal wave?

(c) the quality of the note.
Figure shows four waves A, B, C, and D
Name the wave which shows

(c) a shrill note.
How does frequency affect a musical sound?
What is meant by the ‘pitch’ of a note? Does it depend on the loudness or ‘quality’ of the ‘note’? How is pitch ‘related’ with frequency?
Two musical notes of the same pitch and loudness are played on a violin and a piano. Their waveforms are as shown in the figure below:
What does the intensity of sound depend upon?
