A Monochromatic Light Source Illuminates a Double Slit and the Resulting

question 31

Multiple Choice

A monochromatic light source illuminates a double slit and the resulting interference pattern is observed on a distant screen. Let d = center-to-center slit spacing, a = individual slit width, D = screen-to-slit distance, adjacent dark line spacing in the interference pattern. The wavelength of the light is then:
