• At the focus

• On the reflecting surface

• In front of the mirror

Which mirror always forms a virtual, erect, and diminished image?

• Concave

• Convex

• Parabolic

The principal focus of a convex lens is:

• Behind the lens

• At the lens’ surface

• On the object side

• In front of the lens

The distance from the pole of the mirror to the focus is called:

• Focal length

• Radius of curvature

• Principal axis

• Aperture

Which of these lenses can converge parallel rays of light?

• Same size and real

• Magnified and virtual

• Reduced and real

A real image formed by a mirror is always:

• On the same side as the object

• Inverted and can be projected

• Upright and virtual

The focal length of a plane mirror is:
