Define refraction |
Refraction is the bending or changing of light when it travels from one medium into another |
|
|
Ture or false : optical density is the same as physical density |
False |
|
|
The higher the optical density |
The slower the movement of light |
|
|
Laws of reflection : when one light moves from one medium into another of greater optical density |
The reflected ray will bend towards the normal |
|
|
Laws of reflection: when one light moves from one medium into another of lower optical density |
The reflected ray bends away from the medium |
|
|
Optical density |
Is the tendency for materials to absorb energy before re-emitting |
