As light moves through the air and enters the water of a lake how will it behave?

• Light will speed up as it moves from the air into the water, causing it to refract.

• Light will travel in a straight line from the air into the water, causing it to reflect.

• Light will travel in a straight line from the water into the air, causing it to reflect.

• Light will slow down as it moves from the air into the water, causing it to refract.

During a fireworks show, light and sound waves travel through the air. Which statement describes what you would experience as an observer?

• Sound travels faster than light in a gas, so you hear the display before you see it.

• Light travels faster than sound in a gas, so you see the display before you hear it.

• Sound travels slower than light in a gas, so you hear the display before you see it.

• Light travels slower than sound in a gas, so you see the display at the same time as you hear it.
