A convex mirror of focal length 'f' is placed at the origin with its reflecting surface towards the negative x-axis . Choose the correct graps between 'v' and 'u' for u`lt 0`.

Choose the correct relation between u, v and r for a spherical mirror:

A convex mirror has focal length f. An object is placed at a distance u from the mirror. The condition under which diminished image will be formed is

An object is placed midway between a concave mirror of focal length f and a convex mirror of focal length f. The distance between the two mirrors is 6f. Trace the ray that is first incident on the concave mirror and then the convex mirror.

An object is placed midway between a concave mirror of focal length f and a convex mirror of focal length f. The distance between the two mirrors is 6f. Trace the ray that is first incident on the concave mirror and then the convex mirror.

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.

a concave mirror of focal length 20 cm and a convex mirror of focal length 15 cm are placed 50 cm apart, such that the two mirrors face eaachother. An object is placed exactly midway between them. Fing the nature and position of image formed by reflection first at concave mirror and then at convex mirror.

A convex lens and a convex mirror are separated by a distance of 10 cm such that the reflecting surface of the mirror faces the lens. The image of an object placed in front of the convex. Lens at a distance of 20 cm is found to coincide with the object. If the focal length of the convex lens is 15 cm, determine the focal length of the mierror.
