Electric field – basic information
A volume in which there are forces acting on electric charges, is called an electric field. Such a field is created by the separation charges with different marks as a…

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…
