A virtual image is always .................. (inverted/erect) and is formed behind the mirror.

A real image is always erect.

Virtual image are always inverted

The image formed by a concave mirror

The image formed by a plane mirror is

The image formed by a plane mirror is:

The image formed by a convex mirror is

Assertion: A convex mirror always make a virtual image. Reason: The ray always diverge after reflection from the convex mirror.

Images formed by plane mirrors are erect.

(a) If the image formed by a mirror for all positions of the object placed in front of it is always diminished, erect and virtual, state the type of the mirror and also draw a ray diagram to justify your answer. Write one use such mirrors are put to and why? (b) Define the radius of curvature of spherical mirrors. Find the nature and focal length of a spherical mirror whose radius of curvature is +24 cm.

Assertion:Image formed by concave lens is not always virtual. Reason:Image formed by a lens is real if the image is formed in the direction of ray of light with respect to the lens.
