An object is placed at the centre of curvature of a concave mirror. The distance between its image and the pole isSelect an answerAequal to fBbetween f and 2fCequal to 2fDgreater than 2f

Two objects A and B are placed at 15 cm and 25 cm from the pole in front of a concave mirror having radius of curvature 40 cm. The distance between images formed by the mirror is:

The minimum distance between an object and its real image formed by a concave mirror of focal length f is

An object of size 2.0 cm is placed perpendicular to the principal axis of a concave mirror. The distance of the object from the mirror equals the radius of curvature. The size of the image will be ___________.Select an answerA0.5 cmB1.5 cmC1.0 cmD2.0 cm

A concave mirror has a 4-m radius of curvature.  This mirror will focus distant objects at a location that is approximately:A.4 m in front of the mirror.B.4 m behind the mirror.C.2 m in front of the mirror.D.2 m behind the mirror.

For a concave mirror of focal length f, image is 2 times the size of the object. Then the object distance from the mirror may be
