Total internal reflection can be observed while underwater by look up at....

• the surface from a small angle
• the surface from a wide angle
• the surface from a right angle

When light is trapped inside an object rather than having the ability to escape, this can be used to create...

• Friction
• Energy
• Sparkles

For total internal reflection to occur, two conditions must be met?

• The index of refraction must decrease across the boundary in the direction of light refraction
• The angle of incidence of the light ray must exceed the critical angle of the interface.
• All of the above
