The refractive indices of violet and red light are 1.54 and 1.52 respectively. If the angle of prism is 10°, then the angular dispersion is
The angle of minimum deviation measured with a prism is 30° and the angle of prism is 60°. The refractive index of prism material is
If the refractive indices of a prism for red, yellow and violet colours be 1.61, 1.63 and 1.65 respectively, then the dispersive power of the prism will be
The minimum deviation produced by a hollow prism filled with a certain liquid is found to be 30°. The light ray is also found to be refracted at angle of 30°. The refractive index of the liquid is
Minimum deviation is observed with a prism having angle of prism $A$, angle of deviation $\delta $, angle of incidence $i$ and angle of emergence $e$. We then have generally
A thin prism $P_1$ with angle 4° and made from glass of refractive index 1.54 is combined with another thin prism $P_2$ made from glass of refractive index 1.72 to produce dispersion without deviation. The angle of prism $P_2$ is
An achromatic prism is made by combining two prisms ${{P}_{1}}({{\mu }_{v}}=1.523,\,{{\mu }_{r}}=1.515)$ and ${{P}_{2}}({{\mu }_{v}}=1.666,\,{{\mu }_{r}}=1.650)$; where $\mu $ represents the refractive index. If the angle of the prism ${{P}_{1}}$ is 10°, then the angle of the prism $P_2$ will be
Angle of a prism is 30° and its refractive index is $\sqrt{2}$ and one of the surface is silvered. At what angle of incidence, a ray should be incident on one surface so that after reflection from the silvered surface, it retraces its path
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
