A soap film (n = 1.33) is formed in a loop of wire that is mounted vertically is not exactly uniform in thickness because of its weight, but wedge-shaped in cross section. When the film is illuminated with green light of wavelength 540 nm, one sees that a distance of 3.40 cm separates two bright fringes that are 5 orders apart. By how much does the film differ in thickness over this distance?

A child is playing with a bubble wand, which is a large rectangular wire frame that contains a soap film. The child holds the wand vertically, which causes the film to be thinner at the top and thicker at the bottom, forming a wedge shape. Assume a thickness of essentially zero at the top. White light shines on the film with approximately normal incidence. The child views the reflected light from the film and sees the first violet interference band...

PROBLEM (a) Calculate the minimum thickness of a soap-bubble film (n 1.33) that will result in constructive interference in the reflected light if the film is illuminated by light with wavelength 602 nm in free space. (b) Recalculate the minimum thickness for constructive interference when the soap-bubble film is on top of a glass slide with n = 1.50 STRATEGY In part (a) there is only one inversion, so the condition for constructive interference is 2nt (m 1/2) The minimum...

A soap film (n = 1.33) sits on top of a plastic plate (n = 1.37). White light strikes the film nearly perpendicularly. The smallest nonzero film thickness for which the film appears bright due to constructive interference is 153 nm. What color does the film appear? Violet (420 nm) Yellow (580 nm) Red (650 nm) Blue (475 nm) Green (500 nm) Use the Bohr model to find the second longest wavelength of light in the Paschen series for a...

A wire loop 20 cm high is dipped in soap solution and then held vertically to produce a film whose thickness increases linearly from 0 at the top to 1.0 um at the bottom. The film's refractive index is that of water, n = 1.333. See the figure . If the film is illuminated with white light, what portion of it will appear dark? Choose One Answer: A)The top 7.5% of the film is dark. B)The top 15.0% of the...

10.A narrow beam of white light is incident normally on the surface of a triangular silicate flint glass prism with one angle of 90. The index of refraction for violet light is 1.66 and for red light is 1.61. The angle in the prism is equal to 30° of glass. a.

Question 5:
How would dust and oil on the glass plates affect the
results?
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...
