Unformatted text preview: 62. (a) Eq. 37-3 and Eq. 37-12 imply smaller angles for diffraction for smaller wavelengths. This suggests that diffraction effects in general would decrease. (b) Using Eq. 37-3 with m = 1 and solving for 2θ (the angular width of the central diffraction maximum), we find λ 0.50 m = 2 sin−1 = 11◦ . 2θ = 2 sin−1 a 5.0 m (c) A similar calculation yields 0.23◦ for λ = 0.010 m. ...
