Question

If the pressure amplitude in a sound wave is tripled, then by what factor the intensity of sound wave is increased?

Answer 1

Answer:

Nice question mate !!!

From theory of sound waves we get a relation

P₀ = √2 I ρ v

where P₀ = Pressure amplitude

I = Intensity of sound wave

ρ = Density of medium

v = velocity of sound in the medium

Now from this we get that when the pressure amplitude is tripled we make the intensity of sound 9 times.

Answer 2

Answer:

9

Explanation:

Solution :

I=P₀²/2ρv

I₂/ I₁=[(p₀)₂/(p₀)₁]²

=(3)²

=9
