WebMar 15, 2024 · This law takes into account the refractive indices of the two mediums. Prism is a transparent and polished flat optical element that reflects light. These are formed from any transparent material with the wavelengths that they are designed for. The Prism formula in physics is given by, μ = sin A+δm 2 /sin A 2 μ = s i n A + δ m 2 / s i n A 2 WebMar 29, 2024 · The main conditions for total internal reflection are: Light should travel from denser to rarer medium. Angle of incidence should be greater than critical angle Therefore, The refractive index of the core is greater than the refractive index of the cladding.
