Three right angied prisms of refractive indices $\mu _1$,$\mu _2$ and $\mu _3$ are joined together so that the faces of the middle prism are each in contact with one the outside prism.If the ray passes through the composite block undeviated,then
Total reflecting prisms are _____ prism.
An equilateral prism deviates a ray through $45^{\circ}$ for the two angles of incidence differing by $20^{\circ}.$ The angle of incidence is
A light ray is incident normally on one of the refracting faces of a prism and just emerges out grazing the second surface. The relation between angle of the prism and its critical angle is
A ray of light is incident at an angle of $60^{\circ}$ on one face of a prism of angle $30^{\circ}$. The emergent ray of right makes an angle of $30^{\circ}$ with incident ray. The angle made by the emergent ray with second face of prism will be
A right-angled prism is set to deviate a ray of light through $90^o$ . If the same prism is to be used for deviating through $180^o$ , the prism must be turned from the previous set position through the angle :
Two thin prisms are combined to form an achromatic combination.For prism I, $ A=4^{0}, \mu _{R}=1.35, \mu _{Y}=1.40, \mu _{\nu}=1.42 . $ For prism II $ \mu _{R}=1.7, \mu _{\gamma}=1.8 $ and $ \mu _{R}=1.9 . $ Find the prism angle of prism II and the net mean deviation.
When light rays are incident on a prism at an angle of $45^o$, the minimum deviation is obtained. If the refractive index of the material of the prism is $\sqrt 3$, then the angle of prism will be
The angle of minimum deviation produced by an equilateral prism is $46^0$. The refractive index of material of the prism.
The dispersive powers of flint glass and crown glass are $0.053$ and $0.034 $and respectively and their mean refractive indices are $1.68 $ and $1.53$for white light. Calculate the angle of the flint prism required to form an achromatic combination with a crown glass of refracting angle $4^0$
