^Dispersive power
^Dispersive power It is independent of A but depends upon nature μmaterial. From a single prism it is not possible […]
^Angle of dispersion
θ = δv – δr = [μv – μr] A
^Small angle deviation
^Small angle deviation δ = A (μ – 1) δ depends on i, A, μprism, μmedium, The cause of dispersion […]
^Maximum deviation
^Maximum deviation A prism shows maximum deviation when incidence angle is maximum i.e. 900, also then δmax. = 900 + […]
^Minimum deviation
^Minimum deviation If a light ray is incident at an angle then it shows minimum deviation, also then 1. 2. […]
^Deviation of the emergent ray
^Deviation of the emergent ray Incident ray deviates clockwise towards the base at first face by amount δ1 (= i1 […]
^Prism
^Prism Prism angle A is also called refracting angle & not angle of refraction. A light ray DE in incident […]
^Normal shift
^Normal shift Consider on object O in medium 1 (μ1 > μ2) & observer with eye E in medium 2.
^Critical angle
^Critical angle It is that angle of incidence (i = C) at which a ray going from denser to rare […]
