Vedclass · Answer

(C) Dispersion is the phenomenon of splitting of white light into its constituent colours.In a medium like glass, the refractive index $(n)$ depends on the wavelength $(\lambda)$ of the light, a property known as dispersion.The speed of light in a medium is given by $v = c/n$.Since different colours (wavelengths) have different refractive indices in the flint glass, they travel at different speeds $(v)$ within the prism.This difference in speed leads to different angles of deviation for each colour, causing the light to disperse.Therefore, the correct reason is that light of different colours travels with different speeds in the glass medium.

We use a flint glass prism to disperse polychromatic light because light of different colours:

For flint and crown glass prisms,the prism angles are $A'$ and $A$ respectively. When they are used to produce dispersion without deviation,the ratio $A'/A$ will be:

$A$ thin prism of glass is placed in air and water successively. If $_a\mu _g = 3/2$ and $_a\mu _w = 4/3$,then the ratio of the deviation produced by the prism for a small angle of incidence when placed in air and water is

Derive ${D_m} = A({n_{21}} - 1)$ for a thin prism.

$A$ prism of refractive index $\sqrt{2}$ has a refracting angle of $60^{\circ}$. In order for a ray to suffer minimum deviation,it should be incident at an angle of .......$^{\circ}$.
