Question

Loudness of sound depends upon-
(a) Wave length
(b) Speed of sound
(c) Amplitude
(d) None of these

Answer 1

Answer:

speed of sound

Answer 2

Answer:

(c) Amplitude

Explanation:

The loudness of sound is said to depend upon the amplitude of the sound. More is the amplitude of the sound greater will be the loudness of the sound, that means loudness of sound is directly proportional to the amplitude of the sound. Amplitude of the sound depends on, with how much force an object is made to disturb to produce vibrations or sounds. So, the amplitude of sound decides the loudness of sound.
