INTENSITY

Intensity

In physics, intensity is the power transferred per unit area. In the SI system, it has units watts per metre squared . It is used most frequently with waves, in which case the average power transfer over one period of the wave is used. Intensity can be applied to other circumstances where energy is transferred. For example, one could calculate the intensity of the kinetic energy carried by drops of water from a garden sprinkler.

  4. can mean any of radiant intensity, luminous intensity or irradiance
  5. syn. radiance
  6. The severity of an earthquake in terms of its effects on the earth's surface, and buildings. The value depends on the distance from the epicentre, and is not to be confused with the magnitude.
