Measures intensity.

In 1979, the General Conference on Weights and Measures (CGPM) adopted a new definition: “The candela (cd) is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 10 12 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian.”.The Borg Scale of Perceived Exertion. Swedish researcher Gunnar Borg developed the Borg Scale of Perceived Exertion in 1982 to determine exercise intensity based on several physical cues. These cues include breathing pattern, sweat, and fatigue level. The level of exertion is then matched to a number on a 6 to 20 point scale.Jun 19, 2018 · A photometer is an instrument that measures light intensity.
