PART 1: Slits- Single Slit Design an experiment to verify the that for small angles the angular spread is inversely proportional to the ratio of a/入, and collect data 

 HINT:  if w∝1a then wa=const if you graph awversusa. Use your graph to find  

PART 2: Diffraction

• Explain how the aperture geometry relates to the diffraction pattern.
• Predict how changing the wavelength or aperture size affects the diffraction pattern.
