Snell's Law 1

How does light behave as it enters these mediums?

• continue its path as straight line.
• bends toward the normal
• bends away from the normal
• reflects

The measure of how much light refracts is called...

• Refraction
• Law of reflection
• reflected ray
• Index of refraction

barium glass n=1.60
crown glass n=1.523
water n=1.33
diamond n=2.45

When light passes at an angle to the normal from one material into another material in which its speed is lower

• it is bent towards the normal.
• it always lies along the normal.
• it is unaffected.
• it is bent away from the normal.
