Chapter 14 Interference and Diffraction
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. According to the superposition principle, the net displacement is simply given by the vector or the algebraic sum of the individual displacements.
The superposition of the waves is depicted in Figure 14.1.2. Figure 14.1.2 Superposition of two sinusoidal waves. We see that the wave has a maximum amplitude when sin(x+φ)=1, or x =−π/2 φ. The interference there is constructive. On the other hand, destructive interference occurs at x =−π φ=2.61 rad, wheresin(π) =0. 14-3
