Problem 26.07 Coherent light from a sodium-vapor lamp is passed through a filter

Question

Problem 26.07 Coherent light from a sodium-vapor lamp is passed through a filter that blocks everything except for light of a single wavelength. It then falls on two slits separated by 0.420mm. In the resulting interference pattern on a screen 2.30m away, adjacent bright fringes are separated by 2.76mm. Part A What is the wavelength of the light that falls on the slits?

Explanation / Answer

y = lambda L/d

2.76E-3 = lambda*2.3/0.42E-3

lambda = 5.04E-7 m or 504 nm
