Diffraction and Interference a d Single Slit Double Slit
a = 2.5 m a = 5.0 m = .633 m y/yo x
Diffraction also depends on wavelength! a = 2.5 m y/yo x
Missing Peaks!! Diffraction Modifies the Interference Pattern!!
Polarization: Defined as the direction of E-field! Linear, Circular, Elliptical Fig 38-29, p.1226
