Question

if the amplitude of the wave is increased thrice what will happen to the loudness​

Answer 1

Answer:

If the amplitude of the sound is made 3 times its initial value, then its loudness will become nine times its initial value.

Explanation:

Loudness depends on the square of the amplitude of the wave.

That is, Loudness∝(Amplitude) 2.

Thus, when amplitude of the wave is tripled, the loudness increases nine times.

Answer 2

Answer:

loudness₁ ∝ (amplitude)² ...........1   ⇒ loudness₁= amplitude²

so loudness₂ ∝ (3amplitude)²...........2

so ⇒ loudness₂ = 9amplitude²

∴ loudness₂ = 9loudness₁
