If a spherical mirror is immersed in a liquid, its focal length will:

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 5 cm tall is placed 1 m from a concave spherical mirror which has a radius of curvature of 20 cm. The size of the image is:

Sun subtends an angle of 0.5^o at the pole of a concave mirror of radius of curvature 15 m. The diameter of the image of the sun formed by the mirror is

The focal length of a concave mirror is 12 cm. Where should an object of length 4 cm be placed, so that a real image of 1 cm length is formed?

The focal length of a concave mirror is 20cm. Determine where an object must be placed to form an image magnified two times when the image is real

Given a point source of light, which of the following can produce a parallel beam of light

A convex mirror is used to form an image of a real object. Then mark the wrong statement.

The largest distance of the image of a real object from a convex mirror of focal length 20 cm can be

An object is placed at a distance of 25cm from the pole of a convex mirror and a plane mirror is set so that the virtual images formed by two mirrors do not have any parallax. The plane mirror is 20cm from the object. The focal length of the mirror is
