How fast does light travel?

• Infinite speed

What causes light to bend (refract) as it passes from one material into to another?

• it is attracted to the material

• it follows the shape of the material

• its speed changes

This line is the

• normal

• strange

• angle of refraction

This is the

• angle of incidence

• normal

• angle of refraction

This is the

• angle of incidence

• angle of reflection

• angle of refraction

The angle of refraction is always __________ the angle of incidence

• greater than

• smaller than

• the same as
