Biconvex Lens
Biconvex lens is composed of two spherical surfaces of glass-air interfaces. The two circular surfaces are convex, or bulging out, hence the name biconvex lens. History The first evidence of any …

Total Internal Reflection
Total Internal Reflection (TIR) is basically a phenomenon where light rays travel from a more optically denser medium to a less optically denser medium and gets reflected back into the …
Snell’s Law
Snell’s Law also called as Law of Refraction, is usually stated as, , where \(\theta_1\) is angle of incidence and \(\theta_2\) is angle of refraction and n1, n2 are refractive …
Critical Angle
When a ray of light travels from denser to rarer medium it bends away from the normal and as the angle of incidence in denser medium increases, the angle of …
Brewster’s Law
Brewster’s Law gives the exact angle of incidence for different materials and wavelengths of light for which the reflected ray is completely polarised. This angle of incidence is called the …
