Question

which property describes the amount of energy that flows past a given area per unit of time?

Answer 1

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

$I = \frac{E}{St}$

we can also define it as power per unit area

$I = \frac{P}{S}$

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

$I = \frac{1}{2}\rho A^2\omega^2 v_o$

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

So the above property is defined as intensity.
