   What is intensity in physics?

   • where P is the power carried by the wave through area A. 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 1300W / m2 just above the atmosphere.

   What is the SI unit for intensity?

   • The SI unit for intensity is watts per square meter ( W/m2 W/m 2 ). For example, infrared and visible energy from the Sun impinge on Earth at an intensity of 1300 W/m2 1300 W/m 2 just above the atmosphere. There are other intensity-related units in use, too. The most common is the decibel.

   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 ( ). These look similar to the greater than and less than symbols but they are taller and less pointy.
