Pressure variation in a mechanical wave depends upon as

Question

Pressure variation in a mechanical wave depends upon as (A)  propto intensity (B) independent of intensity (C)  propto (1/ textintensity) (D) None of the above

Tardigrade Admin · Accepted Answer

Amplitude of pressure variation pm=B k A and intensity of wave I propto A2 So, pm propto(I)1 / 2 ie, pressure variation propto (intensity) 1 / 2

Q. Pressure variation in a mechanical wave depends upon as

$\propto$ intensity

independent of intensity

$\propto \frac{1}{intensity}$

None of the above

Amplitude of pressure variation
$p_{m} = B k A$
and intensity of wave $I \propto A^{2}$
So, $p_{m} \propto (I)^{1/2}$
ie, pressure variation $\propto$ (intensity) $^{1/2}$

Q. Pressure variation in a mechanical wave depends upon as

∝ intensity

independent of intensity

∝intensity1​

None of the above

Amplitude of pressure variation pm​=BkA and intensity of wave I∝A2 So, pm​∝(I)1/2 ie, pressure variation ∝ (intensity) 1/2

$\propto$ intensity

$\propto \frac{1}{intensity}$

Amplitude of pressure variation
$p_{m} = B k A$
and intensity of wave $I \propto A^{2}$
So, $p_{m} \propto (I)^{1/2}$
