Question

A beam of light rays, each parallel to the optical axis, strikes the surface of a convex spherical mirror of radius -10 cm. Which statement describes the path of the reflected light rays?

a) the light rays appear to diverge from the center of curvature, located 10 cm behind the mirror

b) the light rays converge at the center of curvature, located 10 cm in front of the mirrow

c) the light rays converge at the focal point, located 5 cm in front of the mirror

d) the light rays appear to diverge from the focal point, located 5 cm behind the mirror

An object is placed on the left side of a concave spherical mirror. The mirror reflects light from the object to form a real image. which statment describes the path of the light rays?

a) light rays converge on the right side of the mirror

b) light rays converge on the left side of the mirror

c) light rays appear to diverge from positions on the right side of the mirror

d) light rays appear to diverge from positions on the left side of the mirrow

The end of a glass rod has the shape of a hemisphere of radium 3.2 cm. The hemisphere bulges outward. Point P is in the air along the optical axis at a distance of 9.3 cm in front of the glass rod. What is the image distance of a small object places at point P?
