Question

What happens to sunlight when it strikes a dark (black) surface? How is wavelength affected? Why are the Sun's rays the most powerful in the summer solstice and why is this not the hottest time of the year. What frequencies or color of light are most likely blocked by glass or other material used to contain heat?

Answer 1

I don't know but don't let anyone tell you that the sun get's closer to the earth because it's always the same legnth away.
