Question

The amplitude of a sound is increased by a factor:
a) 2
b) 3
c) 4
d) ½
e) 1/3
f) ¼
Find the change in the loud of the sound with the above changes in amplitude.

Answer 1

Answer:

amplitude of a sound is increased by a factor:2

Explanation:

Amplitude is directly proportional to the experience of loudness. As amplitude increases, loudness increases.

Answer 2

Answer:

Amplitude determines the loudness of a wave. Greater the amplitude, greater is the loudness.

Explanation:

a) 2

b) 3

c) 4

d) ½

e) 1/3

f) ¼

Bcoz amplitude is directly proportional to Loudness.
