You can see your image in a shiny, flat surface because light waves bounce directly back at you and your eyes. This is an example of ________________. 

• Diffraction
• Reflection
• Refraction
• Transparency

• Refraction
• Interference
• Diffraction

When a pencil is placed in a glass of water, the pencil appears broken at the surface of the water. This is because:

• Light wave speeds up when it moves from air to water
• Light wave slows down when it moves from air to water
• Light wave stops when it hits the water
• There is no change in the light wave's speed
