A glass slab (μ=32) is placed infront of a concave mirror as shown in the figure. At what distance x should an object be placed to the left of the slab, such that the final image forms on object itself.

An object is placed in front of a convex mirror. Its image is formed :a) at a distance equal to the object distance in front of the mirror.b) at twice the distance of the object in front of the mirror.c) half the distance of the object in front of the mirror.d) behind the mirror and it’s position varies according to the object dista

For a concave mirror of focal length f, image is 2 times the size of the object. Then the object distance from the mirror may be

A concave mirror of focal length 10 cm and a convex mirror of focal length 15 cm are placed facing each other 40 cm apart. A point object is placed between the mirrors, on their common axis and 15 cm from the concave mirror. Find the distance (in cm) between image and convex mirror. If the image produced by the successive reflections, first at concave mirror and then at convex mirror.

Two objects A and B are placed at 15 cm and 25 cm from the pole in front of a concave mirror having radius of curvature 40 cm. The distance between images formed by the mirror is:40 cm

An object of height 4.5 cm is placed 32 cm in front of a concave mirror with a radius ofcurvature of 19 cm.(i) Draw a ray diagram to show the location of the image formed by the mirror andstate whether the image is real or virtual. [3 marks](ii) Calculate the distance of the image from the mirror. [3 marks](iii) Calculate the magnification of the image
