Fire intensity. n. The amount of energy or heat release per unit time. FireWords uses a non-specific definition of fire intensity that encompasses several specific types of fire intensity measures.
The intensity varies with the distance from the source and the power of the source. Power is a property of the light source that describes the rate at which light energy is emitted by the source. Power is often expressed in units of watts.Table 1 shows the dependence of intensity (I) upon the distance (r) from a 60-watt light bulb.Numbers are rounded to the second decimal place. 1996-2012 The Physics Classroom, All rights reserved. Light Intensity The term intensity is used to describe the rate at which light spreads over a surface of a given area some distance from a source.
