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 a distance of 0.470 mm. In the resulting interference pattern on a screen which is a distance of 2.23 m away, adjacent bright fringes have a separation of 2.79 mm Part A What is the wavelength? A = —| ΑΣΦ ? m
