Wave Optics

1. Young's Two-Slit Interference

• fringes
• order
• $y(n)=\frac{n\lambda L}{d}$
• $\mathrm{\Delta }y=\frac{\lambda L}{d}$

2. Diffraction Grating

• diffraction grating
• spectroscopy
• reflection gratings
• $y(n)=\frac{n\lambda L}{d}$

3. Diffraction

• aperture
• central maximum
• $y(p)=\frac{p\lambda L}{a}$
• $y_{\text{circle}}(p)=1.22\frac{p\lambda L}{a}$

4. Resolution
