Unformatted text preview: Color Separation i. Angle for 1 st side max Δr adj = 2π λ = dsinθ ii. Angle depends on wavelength larger λ => larger θ III. Single-Slit Diffraction a. Bending of waves past obstacle or thru opening b. c. Example 2 i. 10 th side minima = 2π * 10 ii. Δr tb = 20π/2π = 10λ iii. Θ = Intensity I~A 2 I/I = (A/A ) 2 Δδ adj = 2π (Δr adj /λ) Δδ tb = 2π (Δr tb /λ) For a single slit with width a Δr +b = asinθ 4π 3π 2π π 0 π 2π 3π 4π Δδ adj Δδ Δδ A Tot Δδ tb = phase difference between beams coming from top and bottom edges Δδ tb = 2π (Δr tb /λ) Central max: Δδ tb = 0 Minima: Δδ tb = ±2π, ±4π, ±6π, Δδ tb...
