A coherent light is used to illuminate two slits separated by a distance d = 2.1x 10-4 m, see Figure 3.3. The screen is at a distance L = 3.00 m from the slits. The distance on the screen between the second-order bright fringe and the central bright fringe is y = 16.6 mm. Calculate the wavelength of light. %3D second bright fringe y d central bright fringe second bright fringe - Figure 3.3
