Question

If ‘A’ is the amplitude of a soundwave and ‘L’ is the loudness, what will be the loudness if amplitude is made 3A in the same medium​

Answer 1

Answer:

3a

Explanation:

because 3a is the answer

Answer 2

• Amplitude is the maximum height of either the crust or trough in a sound wave.

• Loudness is directly proportional to the square of amplitude and depends.

If amplitude is A,

loudness = A²

∵If amplitude is 3A

loudness = A²

loudness =(3A)²

loudness = 9A²

Therefore is amplitude is 3A, loudness will be 9A.
