A rectangular glass slab of thickness 3 cm and of refractive index 1.5 is placed in front of a concave mirror perpendicularly on its axis. The radius of curvature of the mirror is 10 cm. At what point should an object be placed on the principal axis so that its image will be formed on the object?

The focal length of a concave mirror is 30 cm. An object is placed at a distance of 45 cm in front of the mirror. A plane mirror is placed perpendicularly on the principal axis of the concave mirror in such a way that the object is situated in between the two mirrors. Light rays from the object at first are reflection from the concave mirror and then from the plane mirror. As a result the final image coincides with the object. What is the distance between the two mirros?

An object is placed just at the middle point between concave mirror of radius of curvature 40 cm and a convex mirror of radius of curvature 30 cm facing each other. The mirrors are situated 50 cm apart from each other. The mirrors are situated 50 cm apart from each other. Considering the first reflection occurs in the concave mirror, determine the position and nature of the image formed by this mirror. Next find the position and nature of the image formed by the convex mirror considering the first image for concave mirror as its object.
