Constructive interference occurs here when -
2 tc = n / 2, 3 (n / 2), 5 (n / 2)
we know that, tc = (n / 4) = 106 nm
The next three thicknesses of this film which will be given as :
tc' = 3 (106 nm) = 318 nm
tc'' = 5 (106 nm) = 530 nm
tc''' = 7 (106 nm) = 742 nm

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...
Light of wavelength 541 nm (in vacuum) is incident perpendicularly on a soap film (n = 1.36) suspended in air. What are the two smallest nonzero film thicknesses (in nm) for which reflected light undergoes constructive interference? Let (a) be the smaller of the two values.
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)
Show all work 4. A soap bubble with n-1.33 is illuminated by white light and produces constructive interference for a wavelength of 460 nm. The bubble is in air and is filled with air. a. Sketch the situation indicating where the light is reflected and what the indices of refraction are at each reflection. (You don't need to sketch the entire bubble.) b. Is the reflected wave inverted at the air-to-bubble interface? Explain. c. Is the reflected wave inverted at...
A thin film, with a thickness of 277.1 nm and with air on both sides, is illuminated with a beam of white light. The beam is perpendicular to the film and consists of the full range of wavelengths for the visible spectrum. In the light reflected by the film, light with a wavelength of 632.3 nm undergoes fully constructive interference. At what wavelength does the reflected light undergo fully destructive interference? (Hint: You must make a reasonable assumption about the...
A soap bubble with walls 380 nm thick floats in air. If this bubble is illuminated perpendicularly with sunlight, what wavelength of visible light will be absent in the reflected light? Assume that the index of refraction of the soap film is 1.33. What color will be absent in the reflected light?
Whats the minimum thickness of a soap bubble film on which light of wavelength 500nm shines that will give distractive interference of the reflected light? Nair=1, Nsoap=1.46
Consider a soap bubble ( both side of film is air) of thickness d and n = 1.5. Light of λ = 600 nm is incident on the bubble. Which values of d produce destructive interference?
A soap bubble with walls 382 nm thick floats in air. Part A If this bubble is illuminated perpendicularly with sunlight, what wavelength of visible light will be absent in the reflected light? Assume that the index of refraction of the soap film is 1.33. Part B What color will be absent in the reflected light?
