Definition of intensity of light
Several measures of light are commonly known as intensity: • Radiant intensity, a radiometric quantity measured in watts per steradian (W/sr) • Luminous intensity, a photometric quantity measured in lumens per steradian (lm/sr), or candela (cd) • Irradiance, a radiometric quantity, measured in watts per square meter (W/m ) WebPolarized light waves are light waves in which the vibrations occur in a single plane. The process of transforming unpolarized light into polarized light is known as polarization. There are a variety of methods of polarizing light. The four methods discussed on this page are: Polarization by Transmission.
