4 Plank’s Constant E=h ν =hc/ λ where h=Plank’s Constant, c=speed of light in a vacuum, ν =frequency, λ =wave length, and E=energy of a quantum (photon) 5 Calculating Frequency from Wavelength Sodium emits yellow light at wavelength 589 nm. What is the frequency of this light and what is energy of one photon? C = 3.00 x 10 8 m/s h = 6.626 x 10 -34 J-s 6 Bohr’s Model Electrons in orbits about nucleus Energy is absorbed when electron moves to orbit away from nucleus Energy is emitted when electron falls back towards nucleus Ground state Excited state
