In physics, intensity of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. … Intensity can be applied to other circumstances where energy is transferred.
What is intensity in physics example?
The definition of intensity is valid for any energy in transit, including that carried by waves. The SI unit for intensity is watts per square meter (W/m2). For example, infrared and visible energy from the Sun impinge on Earth at an intensity of 1300 W/m2 just above the atmosphere.

How is intensity measured in physics?
The equation used to calculate this intensity, I, is:I=PA I = P A Where P is the power going through the area, A. The SI unit for intensity is watts per meter squared or,Wm2 W m 2 . This is the general intensity formula, but lets look at it from a sound perspective.
