23. Mythbusters did a test to see which car was hotter in the direct sunlight: a black car or a white car. They left the
car in the sun for four hours and then came back to see the temperature of the car. They found that the
temperature of the black car was ten degrees hotter than the white car. Explain to someone who does not know
about waves and wave behaviors why this is. Your answer should be specific. You should be able to give your
answer to a student in the 4th grade that has no concept of waves and after they read your answer, they understand
why the Mythbusters obtained the results that they did.
