Answer 2

Intensity is defined as rate of energy per unit area.

Step-by-step 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

`I = (E)/(St)`

we can also define it as power per unit area

`I = (P)/(S)`

so here we can solve it further and find that intensity is given as

`I = (1)/(2)\rho A^2\omega^2 v_o`

so on increasing the intensity of wave, we will have more amplitude.

So the above property is defined as intensity.
