In Lloyd's mirror experiment (Fig. 5.13) a light wave emitted directly by the source S (narrow slit) interferes with the wave reflect ed from a mirror M. As a result, an interference fringe pattern is formed on the screen Sc. The source and the mirror are separated by a distance 1 = 100 cm. At a certain position of the source the fringe width on the screen was equal to Ax= 0.25 mm, and after the source was moved away from the mirror plane by Ah = 0.60 mm, the fringe width decreased λ = 1.5 times. Find the wavelength of light.
