Refraction

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

Swimming pools and the ocean look shallower than they really are due to:

• reflection 
• dispersion
• refraction
• total internal reflection

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

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