wave intensity

Question

Intensity of wave proportional to square of:

RankGuru · Accepted Answer

Intensity ($I$) is the power delivered by a wave per unit area. For a harmonic wave:
$I = \frac{1}{2} \rho v \omega^2 A^2$
where:
- $\rho$: density of the medium
- $v$: wave speed
- $\omega$: angular frequency ($2\pi f$)
- $A$: amplitude
The most important takeaway is $I \propto A^2$ and $I \propto f^2$. This scale relationship is fundamental to energy calculations for sound, light, and mechanical vibrations.
