Draw ray diagram to show how a right angeld isosceles prism can be used to deviate the ray through 180^@

Draw a ray diagram to show image formation when the concave mirror produces a real, inverted and magnified image of the object.

Draw a ray diagram to show the refraction of light through a glass prism. Hence obtain the relation for the angle of deviation in terms of the angle of incidence, angle of emergence and the angle of the prism.

Draw a ray diagram to show the image formation by a concave mirror, when the object is kept between its focus and the pole.

Draw a ray diagram to show how the image is formed when the object is placed between f and 2 f distances from a convex lens.Deduce the relation between the distances of he oject and the image from the lens and the focal length of the lens under this condition.

Fig.2.100 shows a convex spherical surface with centre of curature C,separating the two media of refractive indices mu_1 and mu_2 . . Draw a ray diagram showing the formation of imge of a point object O lying on the principal axis.Derive the relationship between the object and image distances in terms of the refractie indices of the wo media and the radius of curvature R of the surface.
