Set 17 Problem 6 In a water tank experiment, water waves are generated with their crests a distance ^ apart and parallel. They pass through two openings in a long wooden board separated by distance d. If a detector is placed at the end of the tank, a distance L beyond the board, what is the closest detector position, relative to the 'straight-through' direction, so that it receives little or no wave action? Assume L > > d, and do not the the small-angle approximation for this problem. Express your answer in terms of the quantities A, d, and L. Detector position = m NO abc sin(x Ox10 Submit Reset Reset All Evaluate numerically for A = 3.6 cm, d = 6.4 cm, and L = 1.77 m. 5 VO Detector position = m NO abc sin(x) Ox10 0.9222 m Submit Reset Reset All
