Activity 14.1: Locate a plane-mirror image and state its measured properties.

Solution & explanation

Place an object in front of a vertical plane mirror and mark its position. Trace or align reflected sight lines and extend them behind the mirror on the diagram. Their apparent intersection is the virtual image. Compare perpendicular distances and heights: image distance equals object distance, with an upright equal-size image. Real rays stay in front; dashed extensions are construction lines.
