$The single slit interference pattern and the double slit interference pattern that are observed are actually due to diffraction as well as interference.$

The single slit interference pattern and the double slit interference pattern that are observed are actually due to diffraction as well as interference.

$Goal: To understand diffraction Objectives: 1)To learn about the results of Young’s Double Slit Experiment 2)To understand when you get maxima and minima.$
