### [Solved] A broad beam of light of wavelength 600 nm is

A broad beam of light of wavelength 600 nm is sent directly downward through the glass plate (n = 1.50) in Figure. That plate and a plastic plate (n = 1.20) form a thin wedge of air that acts as a thin film. [Solved] A laser beam (A = 632.8 nm) is incident on two A laser beam (A = 632.8 nm) is incident on two slits 0.200 mm apart. How far apart are the bright interference fringes on a screen 5.00 m away from the double slits?
