What visible wavelengths of light are strongly reflected from a 390-nm-thick soap bubble?

A soap bubble is essentially a thin film of water surrounded by air. The colors you see in soap bubbles are produced by interference. What visible wavelengths of light are strongly reflected from a 390-nm-thick soap bubble? What color would such a soap bubble appear to be?

In Young’s experiment, monochromatic light of wavelength 600 nm shines on two slits separated by 0.3 mm, producing an interference pattern on a screen that is 2.0 m away. You put a thin sheet of glass (n = 1.5) at the top slit and you observe a dark fringe the central location of the screen. Furthermore, the fourth bright spot on both sides of the central location is missing. (a) Sketch the resulting interference pattern. Precisely state the spacing between...

An photon with a wavelength in the X-ray region of 0.69 nm undergoes Compton scattering by colliding with a free electron. 1) Assume the photon just barely grases the electron, so that the deflect angle, θ, can be considered zero. 1)What is the wavelength of the outgoing photon after the collision? λ' = 2)What the energy of the outgoing photon? Eγ = 3)Now assume the photon deflects off at a small angle of 49o. What is the wavelength of the...

An interference pattern is produced by light with a wavelength 600 nm from a distant source incident on two identical parallel slits separated by a distance (between centers) of 0.560 mm . If the slits are very narrow, what would be the angular position of the first-order, two-slit, interference maxima? What would be the angular position of the second-order, two-slit, interference maxima in this case? Let the slits have a width 0.280 mm . In terms of the intensity I0...

Blue light of wavelength 470 nm is used to illuminate a pair of narrow slits that are 0.020 mm apart and 1.60 m from a screen. (a) What is the angular position of the second-order minimum (dark spot)? (b) What is the distance on the screen between the central maximum and the second-order minimum? (c) The reason there is a dark spot at this location on the screen is because light from one slit has to travel further than light...
