Conductor
Reflection occurs when light:
Changes speed
Bends
Bounces off a surface
Passes through a lens
Refraction occurs when light:
Reflects off a mirror
Travels in a vacuum
Changes direction as it passes into a different medium
Stops moving

Speeds up
Reflects completely
Slows down and bends toward the normal
Continues in a straight line
