Which is the position of minimum deviation in prism?
The ratio of angular dispersion of to the angle of deviation for the mean wavelength is called Dispersive Power. Represented by
Which relation do we use to find the refractive index of material of prism
A prism of refractive index √2 and refractive angle A produces minimum deviation δm of a ray on one face at an angle of incidence 45°. The values of A and δm are respectively
A thin prism P1 with angle 4° and made from glass of refractive index 1.54 is combined with another thin prism P2 made from glass of refractive index 1.72 to produce dispersion without deviation . The angle of prism P2 is:
