Best with a smooth surface If not for this behavior of light, your mirror
would not work!
Light wave changes speed
Most microscopes and some telescopes
use lenses that take advantage of this
behavior of light
This occurs when light bounces off of a
surface
This behavior of light allows the lenses in
your glasses to bend incoming light waves
This occurs when light moves from
medium to another, like water to air
Reflection
Refraction
