When an object is held between pole and focus of a concave mirror, the image formed is.

When an object placed between the pole and focus of a concave mirror the image formed is ------

Use the mirror formula to show that for an object between the pole and focus of a concave mirror, the image formed is virtual .

When the object is at focus of a concave mirror, the image is formed at

When an object is placed between the focus and the pole of a concave mirror, the image formed is

(a) Draw the ray diagram for the formation of image of an object by a convex mirror and use it (along with the sign convention) to derive the mirror formula. (b) Use the mirror formula to show that for an object, kept between the pole and focus of a concave mirror the image appears to be formed behind the mirror.

Draw the course of a rays for tracing image of an object held between pole and principal focus of a concave mirror. State the position and nature of image formed. or Draw the course of rays for tracing image of an object held between optical centre and principal focus of a convex lens. State the nature of image formed.
