The key aspect of two-slit interference is the dependence of the total intensity at point O on the angle θ. Find this intensity I(θ). The formula for intensity is I=(ϵ0c(amplitudeofE)2)/2 Express your answer in terms of Imax, θ, d, and λ, where Imax=2ϵ0cE(r)2. Note: cos2x should be coded as cos(x)^2. In order to make the math as simple as possible, we will define two phases: ϕ=(2π/λ)*(r−ct) and δϕ=(π/λ)dsin(θ) Then Φlower=ϕ+δϕ and Φupper=ϕ−δϕ E=2E(r)cosϕcosδϕ

The diffraction grating is a way of separating or dispersing light of different wavelengths, producing a spectrum of light. The grating interferes light constructively in particular directions: dsinθm=mλdsin⁡θm=mλ For a particular angle, we calculate the wavelength. The grating constant (or line density) is 500 lines per mm -- every millimeter has 500 lines scratched onto it, equally spaced. The quantity d is the distance between the lines, and λ is the light wavelength. In the previous problem, calculate y2, where one of the second-order spots appears on the meter stick. Either that, or show that y2 can't be determined.
