An object is 100 mm in front of a concave mirror which produces an upright image (erect image). The radius of curvature of the mirror is :

An object is placed 40 cm in front of a convex mirror of radius of curvature 20 cm. The image

An object placed 12 cm from the pole of a concave mirror produces a real image magnified four times.Find the radius of curvature of the mirror.

An object is placed at a distance of 40 cm in front of a concave mirror of focal length 20 cm. The image produced is

An object is placed at 20 cm in front of a concave mirror produces three times magnified real image. What is focal length of the concave mirror ?

When an object is placed at 6 cm in front of a concave mirror, its virtual image is formed at 15 cm from the mirror. Find the focal length and radius of curvature of the mirror.

An object of height 5 cm is placed 2 m in front of a concave mirror of radius of curvature 40 cm. The size of image is

If an object is placed at C on the principal axis in front of a concave mirror, the position of the image is………

At where the object is placed to get a virtual image in front of concave mirror.
