🤓 Based on our data, we think this question is relevant for Professor Criss' class at USF.

Solution: A double slit is illuminated with monochromatic light of wavelength 6.00 x 10 2 nm. The m = 0 and m = 1 bright fringes are separated by 3.0 cm on a screen which is located 10.0 m from the slits. What is the separation between the slits? (a) 4.0 x 10-5 m  (b) 8.0 x 10-5 m (c) 2.0 x 10-4 m (d) 2.4 x 10-4 m
