A double slit experiment is conducted with a red laser with wavelength l = 700 nm. The distance between the slits and the viewing screen is L = 2.00 m. Consider two experiments that have different slit spacings: Experiment A with dA = 2.00 μm and Experiment B with dB = 40.0 μm. For each experiment, calculate the following (be sure to keep at least three significant figures in all your intermediate calculations):
a)
Using Δr = d sinθ , calculate the angle, q1, for the first maximum (constructive interference) above the central maximum. Experiment A and Experiment B
b)
Using the angle you calculated in part a) and y = L tanθ , calculate y1, the location on the screen of the first maximum.Experiment A and Experiment B
