Problem: 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. A fringe pattern is observed on a screen 4.8 m from the slits. If there are 5.0 bright fringes on the screen,
Part A: What is the wavelength of the monochromic light?
Please explain your work and steps to find the wavelength of the monochromic light? Thanks.
