Lindsay has collected four two-liter soda bottles in different colors: dark blue, dark green, and light yellow. She fills them with room-temperature water and places them in a sunny spot on the back porch. After two hours, she returns and measures the temperature of the water in the bottles. What can she expect to find?

• The water in the dark blue bottle is the warmest, because blue light has a higher frequency than yellow or green.

• The water in the yellow bottle is the coolest, because lighter colors absorb less heat than darker colors.

• The water in the dark green bottle is the warmest, because green absorbs both yellow and blue wavelengths of light.

• The water in the dark green bottle is the coolest, because there is no green light in sunlight.
