Rank the "colors" of electromagnetic radiation from the smallest (1) to largest (4) amount of energy per photon. Then rank the different "colors" of electromagnetic radiation by shortest (1) to longest (4) wavelength.
Options: ultraviolet, infrared, red, and blue.
I thought it was ultraviolet, blue, red, infrared for both portions of the question, but I am pretty sure I am wrong. I don't know what energy per photon means and its differences to wavelength.
