A thin film of acetone (n =1.25) coats a thick glass plate (n = 1.50).White light is incident normal to the film. In the reflections, fully destructive interference occurs at 600 nm and fully constructive interference at 700 nm. Calculate the thickness of the acetone film.

A thin film of oil (n = 1.15) is located on smooth, wet pavement. When viewed from a direction perpendicular to the pavement, the film reflects most strongly red light at 640 nm and reflects no light at 548 nm. (a) What is the minimum thickness of the oil film? nm(b) Let m1 correspond to the order of the constructive interference and m2 to the order of destructive interference. Obtain a relationship between m1 and m2 that is consistent with the given data.

Calculate the minimum thickness of a soap-bubble film that results in constructive interference in the reflected light if the film is illuminated with light whose wavelength in free space is λ = 600 nm. The index of refraction of the soap film is 1.33.

White light is directed perpendicular to an oil film (n = 1.45). Calculate the minimum non-zero thickness of the film required to eliminate blue (450nm) reflections.

A broad beam of light of wavelength 600 nm is sent directly downward through the glass plate (n = 1.41). That plate and a plastic plate (n = 1.24) form a thin wedge of air that acts as a thin film. An observer looking down through the top plate sees the fringe pattern, with 7 dark fringes, having two centered on the ends. (a) What is the thickness (in m) of wedge at the right end? (b) How many dark fringes will the observer see if the air between the plates is replaced with a liquid with n = 1.35?

A laser beam is incident on two slits with a separation of 0.200 mm. and a screen is placed 5.00 m from the slits. An interference pattern appears on the screen. If the angle from the center fringe to the first bright fringe to the side is 0.181°, what is the wavelength of the laser light?

A thin flake of mica (n = 1.58) is used to cover one slit of a double-slit interference arrangement. The central point on the viewing screen is now occupied by what had been the seventh bright side fringe (m = 7). If l = 550 nm,what is the thickness of the mica?

A thin film of oil (n = 1.30) is located on smooth, wet pavement. When viewed from a direction perpendicular to the pavement, the film reflects most strongly red light at 640 nm and reflects no light at 548 nm. (a) What is the minimum thickness of the oil film? nm (b) Let m₁ correspond to the order of the constructive interference and m₂ to the order of destructive interference. Obtain a relationship between m₁ and m₂ that is consistent with the given data.

A slit of width 0.15 mm is located 10.0 m from a screen. Light with a wavelength of 450 nm passes through this slit. Determine the distance between the first and the third dark fringes on the screen.

In a double-slit interference experiment, the wavelength is 737 nm, the slit separation is 0.180 mm, and the screen is 33.0 cm away from the slits.  What is the linear distance between the sixth order maximum and the third order maximum on the screen in millimeters?
