The intensity of harmonic wave

Question

The intensity of harmonic wave (A) depends upon its frequency and not on its amplitude (B) depends upon its amplitude and not on its frequency (C) depends upon both, its frequency and not on amplitude (D) depends neither on frequency nor on its amplitude

The intensity of wave I=2 π2 a2 n2 ρ v ∴ I propto a2 propto n2 Therefore the intensity of a wave depends upon both, its frequency and amplitude.

Q. The intensity of harmonic wave

depends upon its frequency and not on its amplitude

depends upon its amplitude and not on its frequency

depends upon both, its frequency and not on amplitude

depends neither on frequency nor on its amplitude

The intensity of wave
$I = 2 π^{2} a^{2} n^{2} ρ v$
$∴ I \propto a^{2} \propto n^{2}$
Therefore the intensity of a wave depends upon both, its frequency and amplitude.
