P is a point on the axis of a concave mirror. The image of P, formed by the mirror, coincides with P. A rectangular glass slab of thickness t and refractive index `mu` is now introduced between P and the mirror. For the image of P to coincide with P again, the mirror must be moved

A point object is placed in front of a concave mirror. And its image is found to coincide with its own position. Now a glass slab of thickness 15 cm and refractive index 1.5 is placed in between object and the mirror. In order to form image again at the location of object, it is required to move the object

An object is placed 21 cm in front of a concave mirror of radius of curvature 10cm. A glass slabe of thickness 3cm and refractive index 1.5 is then placed close to the irror in the space between the object and the mirror. The distance of the near surface of the slabe from the mirror is 1cm. The final image from the mirror will be formed at

The image of an object kept at a distance of 30 cm in front of a concave mirror is found to coincide with itself. If a glass slab (mu=1.5) of thickness 3 cm is introduced between the mirror and the object, then a. Identify, in which direction the mirror should be displaced so that the final image may again coincide with the object itself. b. Find the magnitude of displacement.

An object is placed 21 cm in fron of a concave mirror of radius of curvature 20 cm.A glass slab of thicknes 3 cm and refractive index 1.5 is palced close to the mirror in the space between the object and the mirror. Find the position of the final image fromed. The distance of the nearer surface of the slab from the mirror is 10 cm.
