Ray Optics and ...

Three identical isosceles right-angled prism (ABC, BCD and CDE) are placed as shown in the figure $$\displaystyle \angle ABC,\angle BCD\, and\, \angle CDE$$ are $$\displaystyle 90^{\circ}$$ in the given prism respectively. A ray is incident along line AB Refraction takes placed at BC and CD and then it emerges along the line DE $$\displaystyle \mu _{1},\mu _{2}$$ and $$\displaystyle \mu _{3}$$ are the refractive index of prism ABC, BCD and CDE respectively. The relation between $$\displaystyle \mu _{1},\mu _{2}\,and\,\mu _{3}$$ is

Three right angled prisms of refractive indices $$n_1, n_2$$ and $$n_3$$ are fixed together using an optical glue as shown in figure. If a ray passes through the prisms without suffering any deviation, then

The total deviation of the incident ray when it emerges out of the prism is.

The ratio of $$\frac {\theta _1}{\theta _2}$$ is.

There is an equiconvex lens of focal length of $$20   cm$$. If the lens is cut into tow equal parts perpendicular to the optical axis, the focal length of each part will be

A lens is made of flint glass (refractive index = 1.5). When the lens is immersed in a liquid of refractive index 1.25, the focal length :

The diameter of the reflecting surface of spherical mirror is called ..............

A thin prism $$P_1$$ with angle $$6^o$$ and made from glass of refractive index 1.54 is combined with another thin prism $$P_2$$ of refractive index 1.72 to produce dispersion without deviation. The angle of prism $$P_2$$ will be.

Height of the object and height of the image are measured from the:

A ray of light traveling in the air is incident on the plane of a transparent medium. The angle of the incident is 45$$^o$$ and that of refraction is 30$$^o$$. Find the refractive index of the medium.
