Multiple Choice
Double-slit interference: A pair of narrow slits, separated by 1.8 mm, is illuminated by a monochromatic light source. Light waves arrive at the two slits in phase, and a fringe pattern is observed on a screen 4.8 m from the slits. If there are 5.0 complete bright fringes per centimeter on the screen near the center of the pattern, what is the wavelength of the monochromatic light?
A) 550 nm
B) 600 nm
C) 650 nm
D) 700 nm
E) 750 nm
