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.

Q: How do periscopes work?
Periscopes use multiple mirrors to bend and reflect light, allowing viewers to see objects above or around obstacles. They are commonly used in submarines, armored vehicles, and observation towers.

Q: What are reflection nebulae?
Reflection nebulae are interstellar clouds of dust and gas that shine by reflecting the light of nearby stars. Unlike emission nebulae that emit light on their own, reflection nebulae do not produce their light.

Q: How do fiber optics work?
Fiber optics work based on the principle of total internal reflection. Light signals bounce repeatedly off the walls of the optical fiber, ensuring minimal signal loss as they travel through the fiber, enabling high-speed data transmission.
