Refraction

Refraction is the bending of light as it (select all that apply)

• goes from one medium to another

• experiences a change in speed

• scatters off a surface

• bends around corners

What is incorrect about this picture?

• wrong measurement spots

• 1 does not equal 2

• the arrows should go the other way

• 1 should equal 2

Why is the orange angle less than the red angle?

• air has a higher index than water

• water has a higher index than air

• it is just random

• more info is needed

Based on this diagram, the speed of light is faster in...

• air

• water

• the speed of light is the same in both materials
