Unformatted text preview: 42. Referring to problem 41, we note that the angular deviation of a diffracted ray (the angle between the forward extrapolation of the incident ray and its diffracted ray) is ψ + θ. For m = 1, this becomes ψ + θ = ψ + sin−1 λ − sin ψ d where the ratio λ/d = 0.40 using the values given in the problem statement. The graph of this is shown below (with radians used along both axes). 0.9 0.8 0.7 angular_deviation 0.6 0.5 0.4 0 0.2 0.4 0.6 0.8 1 incident_angle 1.2 1.4 ...
