उत्तर
Visite a laughing Gallery:
Activity:
- Visit a laughing gallery in a science centre, science park or village mela.
- Observe the large mirrors present in the gallery.
- Notice your distorted and funny images reflected in these mirrors.
Observation:
- The mirrors create various distorted images of yourself, making you look taller, shorter, wider or thinner.
Explanation:
The mirrors used in laughing galleries are typically curved mirrors:
-
- Concave Mirrors: These mirrors curve inward and can make your image appear larger and closer, or in some cases, upside down.
- Convex Mirrors: These mirrors curve outward and can make your image appear smaller and farther away.
- Distortion Mirrors: These are specially designed with irregular curves to create funny and exaggerated distortions.
Conclusion:
- The funny and distorted images you see in a laughing gallery are created using concave, convex, and specially designed-distortion mirrors. These mirrors manipulate the reflection of light to alter the appearance of the images they reflect, providing an entertaining and educational experience about the properties of curved mirrors.
