Light as a wave

incomplete

• Solution to wave problem with ansatz
• Interference problems

$$E(d,0)=e^{ik{d}_1}(1+e^{ik\Delta d})$$

• Double slit problem
  • Constructive Interference
  • Maxima and Minima

$$d\sin (\theta )=n\lambda$$

• Single Slit problem
  • Large central maxima (~20x surrounding)

$$a\sin (\theta )=m\lambda$$

• M is for minima, N is for maxima
