Monochromatic light from a point source illuminates two narrow, horizontal parallel slits. The centers of the two slits are a = 0.80 mm apart, as shown in Fig. 40-3. An interference pattern forms on the screen, 50 cm away. In the pattern, the bright and dark fringes are evenly spaced. The distance y shown is 0.304 mm. Compute the wavelength L of the light. |
