Unformatted text preview: 68. Employing Eq. 37-3, we find (with m = 3 and all lengths in µm) θ = sin−1 mλ (3)(0.5) = sin−1 a 2 which yields θ = 48.6◦ . Now, we use the experimental geometry (tan θ = y/D where y locates the minimum relative to the middle of the pattern) to find y = D tan θ = 2.27 m . ...
