Question

What type of image (real or virtual) is formed by a plane mirror, and how is it formed?

Answer

A virtual image. It is formed by the apparent divergence of light rays from a point behind the mirror; the rays do not actually converge there.

Question

A person stands 2 meters in front of a plane mirror. Where does their image appear to be located, and what is the total distance between the person and their image?

Answer

The image appears 2 meters behind the mirror. The total person-to-image distance is 4 meters.

Question

Explain the phenomenon of "lateral inversion" in a plane mirror. Provide a common example.

Answer

Lateral inversion is the left-right reversal of the image. A common example is text appearing backwards in a mirror (e.g., "AMBULANCE" written reversed on vehicle fronts so it reads correctly in a rearview mirror).

Question

If you raise your right hand while facing a plane mirror, which hand does your image appear to raise? What does this demonstrate?

Answer

Your image raises its left hand. This demonstrates lateral inversion, where the image is reversed along the axis parallel to the mirror's surface.

Question

What is the minimum height a vertical, full-length plane mirror must be for a person to see their entire body, and how must it be positioned? (Assume the person's eyes are at a height h from the ground and their total height is H).

Answer

Minimum mirror height = H/2. The top must be placed midway between eye level and the top of the head, and the bottom midway between eye level and the feet.
