During a boring banquet you notice that the fat swimming on top of
your soup is reflecting back cyan, which you remember to be about
500 nm in wavelength. Carefully observing the refraction angles of
your submerged spoon, you figure out that the index of refraction
of the soup is 1.36, while the index of refraction of the fat is
1.43. What is the smallest possible thickness of the fat layer on
top of your soup?

5. Camera lenses (n = 1.5) are often coated with a thin film of magnesium fluoride (n = 1.34). These non-reflective coatings use destructive interference to reduce unwanted reflections. Find the condition for destructive interference in this case, and calculate the minimum thickness required to give destructive interference for light in the middle of the visible spectrum (yellow-green light, λair = 550 nm). 6.

Question 6:
What percentage error would result from miscounting
the bars by one?
EXPERIMENT 10 THIN FILM INTERFERENCE Light from a monochromatic source is shined downward on two glass plates that are separated at one end by a hair. Light that is reflected from the top and bottom surfaces of the wedge-shaped thin film of air undergoes interference, and a series of dark and light lines are seen. By counting the number of dark or light lines over a known...
