The minimum height of a plane mirror to see the full image of a person should be equal to half the height of the person. Placing the mirror at this height ensures that the entire body from head to toe is reflected without any part being cut off.

The minimum height of a plane mirror (B) to see the full image of a person should be half of the person’s height. This placement allows the mirror to reflect the entire body from head to toe without any part of the person being obscured or cut off. When a plane mirror is positioned at this height, the reflected image appears to be the same size and orientation as the actual person standing in front of it. This principle is based on the geometry of reflection, where the angle of incidence equals the angle of reflection, ensuring that the entire visual field of the person can be observed in the mirror. Therefore, for optimal viewing and to see a complete reflection of oneself or others in a plane mirror, positioning it at a height equal to half of the person’s height is recommended, providing an accurate representation without any distortion or missing parts.
