The question as text
A student is investigating monochromatic light passing through a double slit. Bright and dark fringes are produced on a screen as shown in Fig. 2.1. w Fig. 2.1 The distance w between 10 bright fringes is measured. The fringe spacing P between neighbouring bright fringes is then determined. The experiment is repeated for light of different wavelengths m. It is suggested that the fringe spacing P and the wavelength m are related by the equation D P s m = where D is the distance from the double slit to the screen and s is the slit separation.
