All physical systems tends towards a configuration of lowest energy

e Electromagnetic waves – The rules… 1)Electron oscillations in metals create EM waves 2)Light waves are EM waves 3)Light only has certain frequencies of EM waves 4)Non-metals can produce EM waves

e Electromagnetic waves – The rules… 5)Electrons act like particles AND waves 6)Confining electron movement to atoms create specific energies and frequencies of EM waves. 7)Atoms emit/absorb light with specific energies or frequencies which correspond to differences in their energy levels

1.Measure the wavelength = ________ meters 2.Frequency = 2,450,000,000 Hz 3.Calculate the speed of light (c) by using the following formula: C=(Wavelength in meters)(Frequency) 4. Calculate the % Error using the known speed of light (299,792,458 m/s) 5. What should the actual wavelength be?
