उत्तर
(i) Loudness
∴ Amplitude of two waves is the same
∴ their loudness is the same i.e. in 1:1
(ii) Pitch
Ratio of frequencies
256 Hz: 512 Hz
∴ Ratio of their pitch = 1:2

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.
