In science, intensity is the magnitude of a quantity per unit area. In physics, intensity is usually used describe the magnitude of waves per unit area. Another way to interpret the intensity of a wave is as the time average of the power of a wave per unit of area.
The Intensity of Light Formula
The intensity formula in physics is {eq}I = \frac {<P>} {A} {/eq}. When studying light waves, power is described in Watts, and because light is so expansive, it is customary to describe area in meters. Replacing the P and A in the intensity formula with Watts and meters, the units of intensity can be expressed as {eq}I = \frac {<W>} {m^2} {/eq}.
Sound Wave Intensity
Sound wave intensity is the amount of sound wave power in a given area, which is usually taken to be the general area of the listener. Just as for light wave intensity, sound wave intensity has units of {eq}\frac {W} {m^2} {/eq}. When discussing sound wave intensity, the loudness of a sound is most commonly used.
