Question

How does the speed of sound change with change in
(i) Amplitude
(ii) Wavelength of sound wave ?

Answer 1

Answer:

(i) No change

(ii) the greater its wavelength, higher the speed of  sound

Answer 2

Speed of sound

Explanation:

The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. In a sense, the amplitude is the distance from rest to crest.

Wavelength of a sound wave is the distance travelled by the sound wave during one complete cycle. It is the distance between two crests or two troughs.

When Amplitude changes, speed of sound wave changes. If amplitude increases, speed of sound wave decreases and vice versa.

The wavelength of a wave does not affect the speed at which the wave travels.
