To get three images of a single object, one should have two plane mirrors at an angle of

A man of length h requires a mirror, to see his own complete image of length at least equal to

A light beam is being reflected by using two mirrors, as in a periscope used in submarines. If one of the mirrors rotates by an angle θ, the reflected light will deviate from its original path by the angle

A man having height 6 m. He observes image of 2 m height erect, then mirror used is

Two mirrors at an angle θ produce 5 images of a point. The number of images produced when θ is decreased to 30° is

A convex mirror of focal length f forms an image which is 1/n times the object. The distance of the object from the mirror is

A 2.0 cm tall object is placed 15 cm in front of a concave mirror of focal length 10 cm. What is the size and nature of the image

An object is placed in front of a convex mirror of focal length f. Find the maximum and minimum distance of an object from the mirror such that the image formed is real and magnified

A square wire of side 1cm is placed perpendicular to the principal axis of a concave mirror of focal length 15 cm at a distance of 20 cm. The area enclosed by the image of the wire is

A point object is placed on the axis of the concave mirror at a distance of 60 cm from the focal point of the mirror. Its image is formed at the point of object, then focal length of the mirror is
