Review Conceptual Example 2 before attempting this problem. Two slits are 0.158 mm apart. A
mixture of red light (wavelength = 693 nm) and yellow-green light (wavelength = 567 nm) falls on the
slits. A flat observation screen is located 2.42 m away. What is the distance on the screen between
the third-order red fringe and the third-order yellow-green fringe?
m = 3
m = 3
m = 0
m = 3
m = 3
Fringes on observation screen
A film of oil lies on wet pavement. The refractive index of the oil exceeds that of the water. The film
has the minimum nonzero thickness such that it appears dark due to destructive interference when
viewed in visible light with wavelength 643 nm in vacuum. Assuming that the visible spectrum
extends from 380 to 750 nm, what is the longest visible wavelength (in vacuum) for which the film
will appear bright due to constructive interference?
