A person AB of height 170 cm is standing in front of a plane mirror. His eyes are at height 164 cm. At what distance from P should a hole be made in the mirror so that he cannot see his hairs?

The figure shows two parallel plane mirrors placed 10cm apart. An object O is placed 7cm from mirror M₁. Then the distance of final image formed from mirror M₁ is

A spherical concave mirror of focal length 10 cm is cut in two equal halves and is separated by a distance 4 mm as shown. A small object is kept at 30 cm from the mirrors and between the two halves as shown.

The distance between the images by halves of mirror will be

A man is sitting in a room at 2 m from a wall W₁ wants to see the full height of the wall W₂ behind him 4 m high and 6 m away from the facing wall W₁. What is the minimum vertical length of mirror on the facing wall required for the purpose?

When a plane mirror is placed horizontally on a level ground at a distance of 60 m from the foot of a tower, the top of the tower and its image in the mirror subtend an angle of 90^o at the eye. The height of the tower will be

A ray of light fails on a plane mirror. When the mirror is turned, about an axis which is at right angle to the plane of the mirror through 20^o the angle between the incident ray and new reflected ray is 45^o. The angle between the incident ray and original reflected ray was therefore:

Find the distance between the object and its doubly magnified real image by a concave mirror of focal length f .

The reflection surface of a plane mirror is vertical. A particle is projected in a vertical plane which is also perpendicular to the mirror. The initial velocity of the particle is 10 m/s and the angle of projection is 60⁰. The point of projection is at a distance 5m from particle moves towards the mirror . just before the particle touches the mirror. the velocity of approve of the particle and the image is :

The radius of curvature of a plane mirror of length 40 cm is:

A rod 1.5 m long is placed along the principal axis of a convex mirror of focal length 60 cm. The near end of the rod is 1 m from the pole of the convex mirror. The length of the image of the rod is
