Homework Help: Chemistry (Electrons in Atoms)

Posted by Katie on Monday, May 23, 2011 at 7:09pm.

The wavelength of visible light varies from 0.40 μm to 0.70 μm as the color of the light changes from violet to red. Calculate the energy of a photon whose wavelength is 0.67 μm

HINT: From the wavelength and the speed of light, we can get the frequency. Then the energy is simply hf. Use Planck's constant h in the proper units.
