Chapter 14 Interference and Diffraction Superposition of Young s Double-Slit Example : Double-Slit Intensity Example : Intensity of Three-Slit Single-Slit Example : Single-Slit Intensity of Single-Slit Intensity of Double-Slit Diffraction Diffraction Appendix: Computing the Total Electric Solved Double-Slit Phase Constructive Intensity in Double-Slit Second-Order Bright Intensity in Double-Slit Conceptual Additional Double-Slit Interference - Diffraction Three-Slit Intensity of Double-Slit Secondary Interference - Diffraction 14-1 Interference and Diffraction Superposition of Waves Consider a region in space where two or more waves pass through at the same time.
22 rr21−=()r2+r1(r2−r1)=2drsinθ (14.2.3) In the limit L, i.e., the distance to the screen is much greater than the distance between the slits, the sum of and may be approximated by d r1 r2 rr12+ ≈2r, and the path difference becomes δ=rr21−≈dsinθ (14.2.4) In this limit, the two rays and are essentially treated as being parallel (see Figure
