The object distance u
A convex lens of focal length 15 cm and a concave mirror of focal length 30 cm are kept with their optic axes PQ and RS parallel but separated in vertical direction by 0.6 cm as shown in Figure. The distance between the lens and mirror is 30cm. An upright object Ab of height 1.2 cm is placed on the optics axis PQ of the lens at a distance of 20 cm from the lens. If A′B′ is the image after refraction from the lens and reflection from the mirror, find the distance of A′B′ from the pole of the mirror and obtain its magnification. Also, locate positions of A′ and B′ with respect to the optic axis RS.

A biconvex thin lens is prepared from glass of refractive index μ2 = 3/2. The two conducting surfaces have equal radii of 20 cm each. One of the the surface is silvered from outside to make it reflecting. It is placed in a medium of refractive index μ1=5/3. It acts as a
