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 0.510 millimeter. In the resulting interference pattern on a screen 2.24 meter away, adjacent bright fringes are separated by 2.84 millimeter.
Find the wavelength of light that falls on slits?
Answer in nm.
