Embibe Experts Solutions for Chapter: Ray Optics, Exercise 3: Exercise-3

A beam of light consisting of red, green and blue colours is incident on a right angled prism. The refractive index of the material of the prism for the above red, green and blue wavelengths are $1.39, 1.44$ and $1.47,$ respectively.

The prism wil:

A transparent solid cylindrical rod has a refractive index of $\frac{2}{\sqrt{3}}$. It is surrounded by air. A light ray is incident at the mid-point of one end of the rod as shown in the figure.

The incident angle $\left(\theta \right)$ for when the light ray grazes along the wall of the rod is:

The graph between angle of deviation $\left(\delta \right)$ and angle of incidence (i) for a triangular prism is represented by:

Monochromatic light is incident on a glass prism of angle $A$. If the refractive index of the material of the prism is $\mu$, a ray, incident at an angle $\theta$, on the face $AB$ would get transmitted through the face $AC$ of the prism provided.

Consider a tank made of glass (refractive index $1.5$) with a thick bottom. It is filled with a liquid of refractive index $\mu .$ A student finds that, irrespective of what the incident angle $i$ (see figure) is for a beam of light entering the liquid, the light reflected from the liquid glass interface is never completely polarized. For this to happen, the minimum value of $\mu$ is:

What is the position and nature of the image formed by the lens combination shown in the figure? $\left(f_1, f_2\right.$ are focal lengths)

A point source of light $S$ is placed at a distance $L$ in front of the centre of plane mirror of width d which is hanging vertically on a wall. A man walks in front of the mirror along a line parallel to the mirror, at a distance $2 L$ as shown below. The distance over which the man can see the image of the light source in the mirror is 

Formation of real image using a biconvex lens is shown below.

If the whole set up is immersed in water, what will one observe
