What is the smallest thickness d of a soap film (n=1.42) that gives a maximal reflection if illuminated by a green light ( =700nm)? ( use interference condition for the light reflected from the top and bottom sides of the film taking into account wavelenght/2 phase change upon reflection)
Homework Answers
light travels through air and strikes a soap film. The air has a
refractive index of 1 (
) and the film has an index that is larger
than 1 (
). The reflection that occurs at the upper
boundary of the film (the air-film boundary) will introduce a
180

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...

2. Consider a soap film (n = 140) that is hanging in a soap bubble wand. Air is on either side of the soap film. The thickness of the film near the top of the wand is very small (e.g. <<400 nm) and increases monotonically in the downward direction. Suppose that white light is normally incident upon the soap film, and that we look at the light reflected by the film: a. Show why the film...
