The effect of a mirror on perceived height depends entirely on the type of mirror used.
Understanding Mirror Types and Their Effects
Not all mirrors are created equal; they come in different shapes, each impacting how we see our reflection. Here's a breakdown:
-
Plane Mirrors: These are the most common type, like the ones in your bathroom. They show your reflection accurately without distortion. A plane mirror does not make you look taller or shorter; it reflects your actual height.
-
Convex Mirrors: Convex mirrors curve outwards. This shape causes the reflected image to appear smaller and more compact. Therefore, a convex mirror would make a person look shorter.
-
Concave Mirrors: Concave mirrors curve inwards. These mirrors, in contrast to convex mirrors, can make a person look taller. This is because they magnify the reflected image.
According to reference material provided on 07-Jan-2019, "convex mirror makes a person look shorter on the other hand concave mirror makes a person look taller."
How Mirrors Affect Perceived Height
| Mirror Type | Effect on Height | Example |
|---|---|---|
| Plane Mirror | No Change | Bathroom mirror |
| Convex Mirror | Shorter | Security mirrors in stores |
| Concave Mirror | Taller | Some makeup mirrors |
Practical Insights
- If you're trying to assess your actual height, a plane mirror offers the most accurate reflection.
- Be mindful that many mirrors, especially in public places, might not be plane mirrors, and the reflection they provide may be distorted.
- The extent to which a concave mirror makes you look taller depends on its curvature and your distance from the mirror.
Conclusion
While a standard plane mirror will show your actual height, a concave mirror is specifically designed to make a person look taller. Conversely, a convex mirror would make you appear shorter.
