A prism $(\mu =1.5)$has the refracting angle of 30°. The deviation of a monochromatic ray incident normally on its one surface will be (sin48° 36' = 0.75)

Q. A prism $(\mu =1.5)$ has the refracting angle of ${30}^{\circ }$. The deviation of a monochromatic ray incident normally on its one surface will be $(sin{48}^{\circ }{36}^{\prime }=0.75)$

Q. An equilateral prism has refractive index as 1.5. The angle of deviation of the ray is 10n degrees, if a ray is incident normally on a surface. Find n.

Q. A ray of light is incident normally on one face of an equilateral prism of refractive index $1.5$.
The angle of deviation is:

Q. A glass prism has refractive index $\sqrt{2}$ and refracting angle ${30}^{\circ }$. One of the refracting surface of the prism is silvered. A beam of monochromatic light will retrace it path if its angle of incidence on the unsilvered refracting surface of the prism is

Q. A ray of light is incident on a refracting face of a glass prism of refractive angle ${30}^o$. If the ray emerges normally from the second refracting surface, the angle of incidence is ${[}^a{\mu }_g=1.5]$
