Why are mirrors backed with silver?
To avoid spoiling of mirror in rough handling The silver is the reflective surface - its what makes a mirror reflective.
Is glass reflective?
Whenever light, while traveling through a medium such as air, encounters a substance with a different index of refraction, some light will pass and some will reflect off the surface. The angle, and the difference in the two indexes will determine the reflective properties of the glass. Specifically, light is composed of alternating electromagnetic waves. When you solve Maxwell's equations for these waves encountering a surface, reflection is discovered.
What is the light ray that travels toward a reflective surface?
normal
How does reflective light allow us to see an object?
same way normal light does. it's just normal light bouncing off a reflective surface and onto another surface
Between a mirror and non reflective surface?
Ina mirror, the angles bounce off (reflect) in a 90 degrees angle- in straight lines. On a non- reflective surface, it reflects in any angle.
Why a smooth and shiny surface is required for reflection?
It isn't.... take water for example it isn't "smooth" or "shiny" but has reflective properties
What are the properties of gallium?
It is highly reflective and hard
How are reflective properties of light useful?
theyre not
Which indicates the imaginary line that extends straight out from the center of a reflective surface?
The imaginary line that extends straight out from the center of a reflective surface is the optical axis.
Which term indicates the imaginary line that extends straight out from from the center of a reflective surface?
The imaginary line that extends straight out from the center of a reflective surface is the optical axis.
Why does a moon appear to give off a bright white light when it doesn't produce its own light?
The moon reflects the light from the Sun, slightly tinted by the reflective properties of the Moon's surface.
What does a rock have to make it shiny?
It has a polished reflective surface.
What is matte surface?
A matte surface is non-reflective. It is the opposite of shiny.
Which term indicates the imaginary line that extends straight out from the center of a reflective surface?
The imaginary line that extends straight out from the center of a reflective surface is the optical axis.

What reflective surface do you only find in cold places?
Ice!
What is the light ray that travels toward a reflective surface?
