Infrared, Visible Light and Ultraviolet and Microwaves are all important forms of radiation. Which of the following statements regarding radiation is incorrect. Carbon dioxide and other greenhouse gases heat up the atmosphere by absorbing specific frequencies in the Infrared portion of the electromagnetic spectrum. Microwaves are able to heat food because their frequency can cause water molecules to vibrate and rotate. Solar panels work because Ultraviolet light is able to free electrons from the surfaces of certain metals. We see color based on the wavelength of visible light that is absorbed by objects.

Answer 1

The incorrect statement is: **We see color based on the wavelength of visible light that is *absorbed* by objects.**We see color based on the wavelength of visible light that is *reflected* by objects. Objects absorb certain wavelengths of light and reflect others. The reflected wavelengths are what our eyes perceive as color. For example, a red apple absorbs all colors *except* red, which it reflects back to our eyes.
