Answer:
Intensity is defined as rate of energy per unit area.
Explanation:
As we know that intensity of wave is defined as the energy of wave passing through a given cross-section per unit time.
so it is defined as
[tex]I = \frac{E}{St}[/tex]
we can also define it as power per unit area
[tex]I = \frac{P}{S}[/tex]
so here we can solve it further and find that intensity is given as
[tex]I = \frac{1}{2}\rho A^2\omega^2 v_o[/tex]
so on increasing the intensity of wave, we will have more amplitude.
So the above property is defined as intensity.
