For a material medium, the values of refractive index for violet and colours are given as `n_(v) =1.56 and n_r=1.44`. The dispersive power of a prism made out of this material is

A medium has n_v = 1.56, n_r=1.44 . Then its dispersive power is:

For a material the refractive indices for red violet and yellow colour light are respectively 1.52, 1.64 and 1.60 The dispersive power of the material is

The dispersive power ( omega ) of the material of prism is given by

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 indices for violet, yellow and red colours for a flint glass prism are 1.634, 1.623 and 1.616. Calculate the dispersive power of the prism material.

For a medium, refractive indices for violet, red and yellow are 1.62, 1.52 and 1.55 respectively, then dispersive power of medium will be

The refractive indices for the light of violet and red colours of any material are 1.66 and 1.64 respectively. If the angle of prism made of this material is 10^(@) , then angular dispersion will be

The refractive indices for the light of violet and red colours of any material are 1.66 and 1.64 respectively. If the angle of prism made of this material is 10^(@) , then angular dispersion will be

When a ray of sun light passes through the prism each colour of light has its own speed in the glass. The seven colours come out of the prism with different angles of deviation. Red deviates least and violet deviates maximum. Thus a prism can disperse a white light into seven colours which is called colour spectrum. For a thin prism the angle of deviation is given as 8 =(n-1) The angle of dispersion is given as 0 = 8 -0. The dispersive power of a prism is 0 mean 8 Using the above ideas give answer the following questions A prism has R.I. for violet and red = 1.523 n = 1.5145. If the angle of prism is A = 2° the dispersive power of the prism is :

Prism angle of a prism is 10^(@) . Their refractive index for red and violet colour is 1.51 and 1.52 respectively. Then find the dispersive power.
