Question 1: A sheet of glass (n=1.50) is coated with a 501-nm-thick layer of oil (n = 1.42). a) For what visible wavelength(s) of light do the reflected waves interfere constructively? b) For what visible wavelength(s) of light do the reflected waves interfere destructively? Question 2: Coherent monochromatic light of wavelength 632.8 nm passes through a pair of thin parallel slits 0.281 mm apart. The figure shows the central portion of the pattern of bright fringes viewed on a screen. What is the distance between the slits and the screen? 2.52 cm Center of pattern Question 3: The experiment described in question 2 above is performed, but this time, a strip of transparent plastic is placed over the left slit. Its presence changes the interference between light waves from the two slits, causing the interference pattern to be shifted across the screen from the original pattern. Explain, clearly but briefly, which way (right or left) the original pattern shifts and why this shift occurs.

Question 4:
The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656 nm (red)
and 486 nm (blue). Light from a hydrogen lamp illuminates a diffraction grating with 500 lines/mm, and the
light is observed on a screen 1.4 m behind the grating. What is the distance between the first-order red and
blue fringes?
