What is the minimum distance between the object and its real image formed by a concave mirror and when is it possible ?

Text Solution

Verified by Experts

The minimum distance between the object and its real image is zero when u = v = 2f, i.e., the object is placed at the centre of curvature of the concave mirror.

The image formed by a concave mirror-

Show that the minimum distance between the object and the screen is 4 times of focal length of a convex lens at the time of real image formation.

State the nature and size of the image formed by a concave mirror of an object at infinity.

A real and inverted image of the same size is formed by a concave mirror when the object is placed-

An object is placed just at the middle point between concave mirror of radius of curvature 40 cm and a convex mirror of radius of curvature 30 cm facing each other. The mirrors are situated 50 cm apart from each other. The mirrors are situated 50 cm apart from each other. Considering the first reflection occurs in the concave mirror, determine the position and nature of the image formed by this mirror. Next find the position and nature of the image formed by the convex mirror considering the first image for concave mirror as its object.

What will be the nature of image in case of concave mirror?

Draw ray diagram to show the image formation of image when object is placed in front of a concave mirror between pole and focus.

The focal length of a concave mirror is 30 cm. An object is placed at a distance of 45 cm in front of the mirror. A plane mirror is placed perpendicularly on the principal axis of the concave mirror in such a way that the object is situated in between the two mirrors. Light rays from the object at first are reflection from the concave mirror and then from the plane mirror. As a result the final image coincides with the object. What is the distance between the two mirros?
