2. Fig 38-4a, p.1207 Diffraction

4. D = a P wave front

5. Phasor Model Where we assume:

6. Note: β =  and E R = E θ

8. These produces the same interference patterns!

9. a b

10. Diffraction from Circular Aperture

12. Single SlitDouble Slit Diffraction and Interference ad

13. y/y o x =.633  m a = 5.0  m a = 2.5  m

14. Diffraction also depends on wavelength! a = 2.5  m x y/y o

15. Missing Peaks!! Diffraction Modifies the Interference Pattern!!
