1. Suppose light falls on double slits separated by 110 µm. d = 110 µm 0 = 0.66° What is the wavelength of the light in nm, if the third-order maximum is at an angle of 0.66°? 2. A laser beam is incident on two slits with separation d = 0.012 mm. A screen is placed L = 1.2 m from the slits. The wavelength of the laser light is A = 2500 Å. 0₁ and 02 are the angles to the first and second bright fringes above the center of the screen. Solve for the numerical value of y, the distance between the two bright fringes on the screen, in meters.
