![5. Consider a double slit experiment conducted with a laser source at 540 nm wavelength. The two slits are separated at a distance of 4 mm. As shown in Figure 3.2, a thin glass plate is placed in front of one of the two slits, resulting in each bright fringe moving to the location of the adjacent bright fringe. Determine the minimum thickness of the glass plate. Assume that the refractive index of the glass is 1.56. Ignore the reflections caused by the glass plate.

You perform a double-slit experiment in order to measure the wavelength of the new laser that you received for your birthday. You set your slit spacing at 1.11 mm and place your screen 8.43 m from the slits. Then, you illuminate the slits with your new toy and find on the screen that the tenth bright fringe is 4.87 cm away from the central bright fringe (counted as the zeroth bright fringe). What is your laser's wavelength 1 expressed in...

A two-slit interference experiment was done where the aperture to screen distance is 1m, wavelength of light is 632nm, fringe spacing is 0.5mm, and the slit separation is found to be 1.26mm. Then, a thin plate of glass of thickness 0.03mm and refractive index n=1.4 is placed over one of the slits. What is the resulting lateral fringe displacement at the screen?
