What is the focal length of a plane mirror ?

What is the value of focal length of a plane 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.

Focal length of a convex mirror is 10 cm

If the focal length of a convex mirror is 25 cm, what is its radius of curvature ?

A convex lens of focal length 10cm is placed 30 cm in front of a second convex lens also of th esame focal length. A plane mirror is placed after the two lenses. Where should a point object be placed in front of the first lens so that it imagees on to itself?

An object of height 2cm is kept 2m in front of a convex lens of focal length 1m. A plane mirror is placed at 3m from the lens on its other side. Find the nature, position, and magnification of the final image that will be seen by an observer looking toward the mirror through the lens.

Focal length of a concave mirror is

A convex lens of focal length f and a plane mirror are y distance apart. An object O is kept on the principal axis of the lens at a distance x from the lens. The values of x and y for the final image of O to fall exactly (position and size) on the object O are :
