A convex mirror of length 1m and a plane mirror are facing each other, if the distance between them is 1m, their images are separated by

A convex mirror of radius of curvature 70 cm and a plane mirror are placed face. The distance of separation between the mirrors is 28 cm. If a point source is placed on the principal axis in between the mirrors, two images are formed in the plane mirror. Determine the distance of the two images from the plane mirror.

A convex mirror and a concave mirror of radius 10cm each are placed 15cm apart facing each other. An object is placed midway between them. If the reflection first takes place in the concave mirror and then in convex mirror, the position of the final image is

A convex mirror offocal length fforms an image which is 1/n times the object. The distance of the object from the mirror is:

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.

An object O is placed in front of a small plane mirror M_(1) and a large convex mirror M_(2) of focal length f . The distance between O and M_(1) is x, and the distance between M_(1) and M_(2) is y. The images of O forned by M_(1) and M_(2) coincide. The magnitude of f is
