The class is about heat, waves, and light. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

Set 17 Problem 6 In a water tank experiment, water waves are generated with their crests a distance A 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 abc sin(x Ox10 Submit Reset Evaluate numerically for A = 3.6 cm, d = 6.4 cm, and L = 1.77 m. 5 Detector position = m abc sin(x) Ox10 Submit Reset
