Properties of Images in Plane Mirrors

Steps:

• Plane mirrors reflect light rays such that the angle of incidence equals the angle of reflection.
• Rays diverge after reflection, so the image appears behind the mirror and cannot be projected on a screen, making it virtual.
• The image is laterally inverted but maintains the same orientation as the object, so it is upright.
• The image size equals the object size, and it is at the same distance behind the mirror as the object is in front.

Why B is correct:

• By the law of reflection, plane mirrors form virtual, upright images that are the same size as the object.

Why the others are wrong:

• A: Images are virtual, not real, and upright, not upside down.
• C: Images are virtual and same size, not real or larger.
• D: Images are same size, not smaller.

Final answer: B
