Refraction is the bending of waves or particles as they transition between different mediums, like air to plexiglass. This phenomenon causes visual effects, such as a fish appearing higher in water than its actual position. Light bends toward the normal when moving from a less dense to a more dense medium and away when the opposite occurs. Total internal reflection, which happens when light moves from a denser to a less dense medium, is crucial in applications like fiber optics and diamond sparkling. Explore various prism types and their unique properties related to refraction.

Definition • Refraction- the bending of a wave or particle as it passes from different mediums
Application • A 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 Normal • When light passes from plexiglass to air, it bends away from the normal.
Total Internal Reflection • Only 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
Applications of Refraction • Fiber optics, polar bear skin, sparkling of diamonds
