Huygens–Fresnel principle
Huygens–Fresnel principle (also known as Huygens principle) says that all wave front points can be considered sources of new spherical waves. The position of the wavefront after at time t…

What is polarization of light?
Polarization (in physics) is limiting transverse wave vector vibrations to some direction. For non-polarised electromagnetic waves, such as visible light, the electric field vibrates in all directions perpendicular to the…
