What is the radius of curvature of plane mirror?

A virtual image of half the size of the object is formed by a convex mirror at a distance of 30 cm from the object. What is the radius of curvature of the mirror?

Define radius of curvature

An object is placed at a distance of 50cm is front of a convex mirror. Now a plane mirror is placed in between the object and the convex mirror, converting the lower half of the convex mirror. If the distance of the plane mirror from the object is 30cm, it is seen that there is no parallax of the images formed by the two mirrors. What is the radius of curvature of the convex mirror?

An image of size 1/n times the object size is formed in a convex mirror. If r is the radius of curvature of the mirror what would be the object distance?

An object is placed 60 cm away from a convex mirror. The size of the image is (1)/(3)rd the size of the object. Determine the radius of curvature of the mirror.

A Cassegrain telescope is built with mirrors 20 mm apart. If the radius of curvature of the large mirror is 220 mm and the small mirror is 140 mm, then where will the final image of an object at infinty be?

An object is placed at a distance of 20 cm in front of a convex mirror. Now a plane mirror is placed in between the object and the convex mirror, convering the lower half of the convex mirror, If the distance of the plane mirror from the object is 15 cm, it is seen that the images formed by the two mirrors coincide. Determine the radius of curvature of the convex mirror.

A planet subtends an angle (6)/(pi) min at the pole of a concave mirror. The diameter of the image of the planet formed by the mirror is 4 mm. Calculate the radius of curvature of the concave mirror

A rectangular glass slab of thickness 3 cm and of refractive index 1.5 is placed in front of a concave mirror perpendicularly on its axis. The radius of curvature of the mirror is 10 cm. At what point should an object be placed on the principal axis so that its image will be formed on the object?
