Verified answer
Early settlers placed diverging reflective or mirrored surfaces behind oil lamps on walls to help to better increase their radiance by reflecting the light that would otherwise be hitting the wall.

Diverging mirrors on oil lamps on walls?
diverging mirrors behind oil lamps lets the light reflect all around the room instead of being reflected as one beam
If a person is in front of a smooth surface from which a sound is reflected where does the sound appear to come from?
The sound would be reflected and seem to come from behind the reflective surface. This is commonly experienced near airports, where the sound of aircraft appears to come from the opposite direction, instead of from the airport.
Why can the image formed by a convex mirror not be projected on a screen?
Beacuse the image is formed behind the mirror after reflection. The image appears to be diverging from the Principal Focus.

Why did early settlers put diverging mirrors behind oil lamps?
When you put a mirror or other item behind a lamp or candle the reflection makes the light produced brighter.

What is impounded surface water?
Impounded surface water is water held behind a dam in the reservoir that the structure creates behind it.
What is mirror made of?
Glass, silver paint (or foil) and black paint. The silver paint or foil reflects the light that hits it, the black paint prevents light from behind washing out the image and helps protect the reflective surface from damage. The glass also helps protect the reflective surface as well as focus the reflective image.AnswerThe elements that make up mirrors are silycon, oxygen, and silver. Modern mirrors are made by vacuum deposition of aluminum onto a smooth base, then covering with glass. The glass makes for a smoother surface and also protects the aluminum from damage. Fundamentally, the plate is placed in a chamber which is then evacuate. Aluminum is vaporized, and condenses on the surface of the plate.Also, aluminum can be vacuum deposited to the glass itself. It is often given a black backing to improve opacity and reflectivity. At one time mercury was used, but no longer due to health an environmental issues.
Does light make a tiger's eye glow in the dark?
Tigers, as with all cats, have a reflective layer behind the retina. This allows them to use the light twice in the retina, making it much easier to see at night. When cat's eyes appear to glow, you are seeing the escaping reflected light from this surface.
What is the principle behind rubber sucker?
It has a flat surface which can stick on smooth surface.
How does mirrors reflects light?
The light shine on any object is either reflected or absorbed into the object. Modern mirror use highly reflective material coated behind the flat glass surface thus the light would bounce off at exact opposite angle and we could see the reflection.
