Consider red light with a wavelength of 690 nm in air that is incident onto two slits such that it gives diffraction fringes that are 1.00 mm apart on a screen at a distance L from the slits. If the screen is moved back by an additional 8.00 cm, the fringes become 1.40 mm apart. What is the separation between the slits? (a) 0.109 mm, (b) 0.138 mm, (c) 0.177 mm, (d) 0.218 mm, (e) 0.276 mm.

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 ,...
