Refraction Power-Point

DefinitionRefraction- the bending of a

wave or particle as it passes from different mediums

ApplicationA fish appears higher than it actually is…

Bending Toward the Normal

When light goes from a less dense to more dense medium, it is bent toward the normal. This is an example of air going to plexiglass.

Bending Away from the NormalWhen light passes from plexiglass to air, it

bends away from the normal.

Total Internal ReflectionOnly occurs when light goes from more dense to

less dense.

Three cases:(1) Refracts- bends away from normal (o-43o)(2) Critical angle- prism(3) Reflection
