intensity

1. Physics
a. a measure of field strength or of the energy transmitted by radiation
b. (of sound in a specified direction) the average rate of flow of sound energy, usually in watts, for one period through unit area at right angles to the specified direction.
2. Geology a measure of the size of an earthquake based on observation of the effects of the shock at the earth's surface. Specified on the Mercalli scale

intensity

1. (radiant intensity) The radiant flux emitted per unit solid angle by a point source in a given direction. It is measured in watts per steradian.
2. Obsolete name for field strength of a magnetic or electric field.

intensity

[in′ten·səd·ē]
(physics)
The strength or amount of a quantity, as of electric field, current, magnetization, radiation, or radioactivity.
The power transmitted by a light or sound wave across a unit area perpendicular to the wave.
