c E B 6 6 8 f = c/ 8 C e - When the EM wave enters the glass, the electric field in the wave causes electrons in the glass to oscillate up & down with frequency f N that is the same as the frequency of wave. f N = f Air Glass

C e - f N = f Glass E B S 6 6 6 Incident Beam: Frequency f & Wavelength 8 = c/ f The electrons in the glass absorb energy from the incident beam, start to oscillate, and then because they are oscillating charges, emit their own EM waves.

C f N = f Glass E B S 6 6 6 Incident Beam: Frequency f & Wavelength 8 = c/ f The waves emitted by the electrons in the glass have frequency f N = f and fan out in almost all directions. (No waves are emitted along the line of oscillation.)

C f N = f Glass E B S 6 6 6 Incident Beam: Frequency f & Wavelength 8 = c/ f The waves emitted by all of the oscillating electrons interfere with each other, destructively in some directions and constructively in other directions. Constructive interference produces . ..
