प्रश्न
Mention two properties of a wave, one property which varies and the other which remains constant when the wave passes from one medium to another.
उत्तर
Here we refer to a mechanical wave, its two properties are:
(i) These waves transmit only energy and momentum through the limited motion of the particles of the medium.
(ii) While transmitting energy, the medium remains unshifted, i.e., only energy is transmitted while particles of the matter of the medium do not travel with the same.
