Total Internal Reflection
Let us consider a ray of light passing from glass to air, that is from a denser medium to a rarer medium. The figure shows that for a small angle of incidence, major part of the incident light is refracted and a small portion is reflected. The refracted ray bends away ..
Brewster's Law (Polarization by Reflection)
When unpolarised light is incident at polarizing angle i p on an interface separating air from a medium of refractive index m then, m = tan i p When the light is incident at polarizing angle ip, the reflected component along OB and refracted component along..
