Question

what is the formula for finding intensity

Answer 1

Answer:

Intensity is defined to be the power per unit area carried by a wave. Power is the rate at which energy is transferred by the wave. In equation form,intensity I is I=PA I = P A , where P is the power through an area A. The SI unit for I is W/m2.

Answer 2

Explanation:

I=\frac{P}{4 \pi r^{2}}

I = intensity

{P} = power

\pi = pi

r = radius
