A point object O is placed in front of a concave mirror of focal length 10cm. A glass slab of refractive index `mu=3//2` and thickness 6cm is inserted between the object and mirror.
Find the position of final image when the distance x shown in Fig... is, (a) 5cm and (b) 20 cm.

A point object O is placed in front of a concave mirror of focal length 10cm. A glass slab of refractive index mu=3//2 and thickness 6cm is inserted between the object and mirror. Q. Find the position and nature of the final image when the distance x shown in figure, is 5cm.

If an object is placed 10 cm in front of a concave mirror of focal length 20 cm, the image will be.

A point object O is placed at a distance of 62 cm in front of a concave mirror of focal length f = 20 cm . A glass slab of refractive index mu = (3)/(2) and thickness 6 cm is inserted between the object and the mirror. Let’s define final image as image formed after the light ray originating from O passes through the slab, gets reflected from the mirror and then again passes through the slab. At what distance d from the mirror, the face AB of the slab can be placed so that the final image is formed inside the slab itself?

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.
