Q. A concave mirror is of hemisphjerical shape with radius 40cm. A thin layer of unknown transparent liquid is poured into mirror. The mirror liquid forms a real image and another real image is formed by the mirror alone. One of them coincides with object and other is at a distance 20 cm from the object in the direction away from mirror.
