A ray of light passing through a prism. If the refracted ray QR is parallel to the base BC, as shown in figure:Draw a graph which shows the variation of d with i.

A ray of light parallel to the principal axis of a spheri cal mirror falls at a point M as shown in the figure,Complete the ray diagram and mark the angle of incidence and angle of reflection

The path of light rays through a convex lens when it is placed in two different media is shown in the figure. What is the relation between the refractive indices mu, mu_1 and mu_2 ?

A ray of light parallel to the principal axis of a spherical mirror falls at a point M as shown in the figure,If focal length of the mirror is 10cm, what is the distance CF in the figure?

A ray of light falls on the side of a prism ABC whose refracting angle Is A. The angles of incklence and refraction at the first face AB is i_1 and r_1 while at the second face AC is i_2 and r_2 If the refractive index of the material of the below prism is 1.5, Find the critical angle of the prism.
