"The candela, symbol cd, is the SI unit of luminous intensity in a given direction. It is defined by taking the fixed numerical value of the luminous efficacy of monochromatic radiation of frequency 540 × 10 12 Hz , K cd , to be 683 when expressed in the unit lm W −1 , which is equal to cd sr W −1 , or cd sr kg −1 m −2 s 3 , where the ...

The height of a wave as measured from its center (normal) position. angle of incidence In geometric optics, the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. The ray can be formed by any wave: optical, acoustic, microwave, X-ray, etc. angle of reflection
