What is the intensity of a wave?
By definition, the intensity (I) of any wave is the time-averaged power ( P ) it transfers per area (A) through some region of space. The traditional way to indicate the time-averaged value of a varying quantity is to enclose it in angle brackets ( ).
Feb 20, 2022 · 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 \((W/m^2)\). For example, infrared and visible energy from the Sun impinge on Earth at an intensity of \(1300 \, W/m^2\) just above the atmosphere.
