Question

Light with a wavelength of 526nm passes through two slits and forms an interference pattern on a screen 9.00m away. If the linear distance on the screen from the central fringe to the first bright fringe above it is 5.56 cm, what is the separation of the slits?

Explanation / Answer

1. Y = mR/d

d = 1*526*10^-9*9/0.0556

d = 0.85 mm
