Refraction

Refraction is defined as

• The bending of light around a corner

• The bending of light as it enters a new material

• The bending of light around a barrier

• The breaking of white light into the colors

Light travels the fastest inside which material?

• Glass (n=1.5)

• Water (n=1.33)

• Diamond (n=2.42)

• Plastic (n=1.2)

Mirages and Rainbows are both a product of

• Diffraction

• Refraction

• Total internal reflection

• Reflection

As light travels from a low density material to a high density material the light will __________

• speeds up and bends toward the normal (smaller angle)

• speeds up and bends away from the normal (bigger angle)

• slows down and bends toward the normal (smaller angle)

• slows down and bends away from the normal (bigger angle)
