FAQs
Q: How do mirrors reflect light?
Mirrors reflect light through a process of absorption and re-emission of photons at the atomic level. When light hits the mirror’s surface, it gets absorbed and then re-emitted, bouncing back and preserving the original image.
Q: What causes the shimmering reflection on water?
The shimmering reflection on water occurs due to the surface waves created by wind or disturbances. These waves act like miniature mirrors, reflecting sunlight and creating the glimmering effect.
Q: Why do gemstones sparkle?
Gemstones sparkle due to the phenomenon of light reflection and refraction within the stone’s structure. When light enters the gem, it reflects off its facets and refracts as it exits, creating a brilliant play of colors.
