For a dense flint glass prism of refracting angle `10^0`, Findthe anangular deviation for extreme colours and the dispersive ppower for dense flint glass. `(n_(red) = 1.712`, `n_(violet) = 1.792`)

For a dense flint glass prism of refracting angle is 10^@ , obtain angular deviation for extreme colours and dispersive power for dense flint glass. (n_(red) = 1.712, n_(viol et) = 1.792)

From the given data set, determine angular dispersion by the prism and dispersive power of the material for extreme colours. n_R = 1.62, n_v = 1.66, s_R = 3.1^@

The refractive index of the prism for violet colour is 1.7 and that for red is 1.65. Then dispersive power of the material of prism is

The refractive index of the prism for violet colour is 1.7 and that for red is 1.65. Then dispersive power of the material of prism is

The net angular dispersion produced without deviation for crown glass (n = 1.56) and flint glass (n = 1.7) is

The net angular dispersion produced without deviation for crown glass (mu = 1.56) and flint glass ( mu = 1.7) is

A crown glass prism of refracting angle A= 6^@ is to be achromatised for red and blue light using a flint glass prism. Find the angle of flint glass prism (A') and also, the mean deviation from the following data : mu_b=1.531 mu_r=1.520 mu'_b=1.684 mu'_r=1.662

To produce deviation without dispersion with the help of crown glass prism of refracting angle (A) and flint glass (A') they must be related as
