Step 1: Identify the formula for phase difference in Young's double-slit experiment. The phase difference ( ) between two waves is related to their path difference ( x) by the formula: = (2)/() x where is the wavelength of light. Step 2: Determine the path difference for a bright fringe. For a bright fringe (constructive interference), the path difference is an integer multiple of the wavelength: x = m where m is the order of the bright fringe (m = 0, 1, 2, ). Step 3: Find the order of the third bright fringe. The central bright fringe corresponds to m=0. The first bright fringe corresponds to m=1. The second bright fringe corresponds to m=2. The third bright fringe corresponds to m=3. So, for the third bright fringe, m=3. Step 4: Calculate the path difference for the third bright fringe. Using m=3, the path difference is: x = 3 Step 5: Calculate the phase difference for the third bright fringe. Substitute x = 3 into the phase difference formula: = (2)/() (3) = 6 The wavelength = 6000 Å is given but is not required for this calculation as it cancels out. The final answer is (d) 6 3 done, 2 left today. You're making progress.
