The average human eye can see visible light between 760. nm and 380. nm.
a. What is the frequency of each wavelength
b. What is the energy of the photons corresponding to each wavelength?
c. Place the following parts of the electromagnetic spectrum in order of decreasing wavelength: radio, gamma rays, ultra-violet, visible, x-rays, infra red. c = 2.997x108 m/s h = 6.626x10-34 J?s = 4.135x10-15 eV?s
