A concave mirror of focal length `20cm` is placed inside water with its shining surface upwards and principla axis vertical as shown in Fig. Rays are incident parallel to the principa, axis of concave mirror. Find the position of final image.

A concave mirror is placed inside water its shining surface upwards and principal axis vertical as shown in figure. Rays are incient parallel to the principal axis of the concave mirror. Find the position of the final image.

If an object is placed at C on the principal axis in front of a concave mirror, the position of the image is………

A concave lens of focal length 20 cm placed in contact with ah plane mirror acts as a convex mirror of focal length

A concave mirror of focal length 36 cm and a convex mirror of focal length 20 cm are placed face to face on the same axis at a distance of separation 80 cm. An object is placed at a distance 20 cm in front of the convex mirror. Determine the position of the images (i) first by the reflection in convex mirror and then in the concave mirror and (ii) first by the reflection in concave mirror and then in the convex mirror.

Shown in Fig. is a vertically erect object placed on the optic axis at a distance (5//2)f from a concave mirror of focal length f. If a plane mirror is placed perpendicular to the optic axis at a distanc (4//3)f from the pole, facing concave mirror, find the position and nature of the final image formed.

Shown in Fig. is a vertically erect object placed on the optic axis at a distance (5//2)f from a concave mirror of focal length f. If a plane mirror is placed perpendicular to the optic axis at a distanc (4//3)f from the pole, facing concave mirror, find the position and nature of the final image formed.
