Light traveling in air is incident perpendicular to the surface of a thin film of plastic that is on the surface of a sheet of glass. In the reflected light, two dark consecutive overlapping fringes are observed corresponding to wavelengths 6.1 x 10-7 m and 6.0 x 10-7m. Access 23 !! Thin-Film Interference video and text solutions to help you complete your homework. What visible wavelengths of light are strongly reflected from a 390-nm-thick soap bubble? An oil tanker spills a large amount of oil (n = 1.45) into the sea (n = 1.33).A. What is the thinnest film that pro... Q. A thin film with thickness t coats a flat piece of glass. White light is incident normally on a thin soap film (n = 1.33) suspended in air.What are the two minimum thicknesses that will destructively refle... Q. Note also that there is an additional λ /2 phase shift when light reflects from a medium with a greater index of refraction. Calculate the thickness of the film. Clutch Prep is not sponsored or endorsed by any college or university. If you look down on the oil spill from overhead, what predominant ... Q. Thin-Film Interference problems. Coherent... Q. If a thin film has a thickness that is(a) 1/4 of a wavelength, constructive interference will always occur. Be certain to use the wavelength in the medium involved, since it differs from the wavelength in vacuum. An oil film that is 400 nm thick is on top of water. What color in the visible spectrum and the wavelength is... Q. What are(a) the bubble thickness just as the last vesti... Q. A layer of benzene (n = 1.50) that is 300 nm thick is floating on water (n = 1.33). A practical application of this effect are anti-glare films. (b) 1/4 of a wavelength, destructive int... Q. Get a better grade with hundreds of hours of expert tutoring videos for your textbook. The colors you see in soap bubbles are produced by interference. A layer of benzene that has thickness t is floating on water. A thin film of soap solution is illuminated by white light at an angle of incidence i = sin-1(4/5). (a) What visi... Q. The colors that you see in soap bubbles are produced by interf... Q. Master even the most complex scientific problems with our step-by-step explanation videos. The oil has n = 1.2 and the water has n = 1.33. Given, µ = 4/3, λ1 = 6.1 x 10-7 m λ2 = 6.0 x 10-7m solution: Sin i = 4/5 µ = Sin i / Sin r Sin r = sin i / µ = ⅘ / 4/3 = sin r = ⅗ = 0.6 cos r = √1 – sin2r = 0.8 Given two consecutive fringes are overlapping, nλ1 = (n + 1)… Consider a very thin layer of oil (... Q. 1. There is air above the film. If thin film interference is involved, take note of the path length difference between the two rays that interfere. A light of wavelength 500 nm is shown on the flat ... Q. A soap bubble is essentially a thin film of water surrounded by air. What color would such a soap bubble appear to be? A 12 cm radius sphere of glass (n = 1.33) is cut in half and placed convex-side down on a table. When light strikes a thin film with air on both sides, if the film allows for no light to be reflected (i.e. 1. If you forgot your password, you can reset it. Follow these steps to solve this problem: A very thin oil film (noil = 1.25) floats on water (nwater = 1.33). White light is incident normally on a thin soap film (n = 1.33) suspended in air.What are the two minimum thicknesses that will constructively refl... Q. The center spot of Newton’s rings is dark. A thin film with thickness t is placed on the surface of a flat piece of glass. The refractive index for soap solution is 4/3. B) both the front and back surface... Q. There is air above the benzene. Q. Thin-film interference is responsible for the fact that certain birds and inspects can appear different colors. By registering, I agree to the Terms of Service and Privacy Policy. Light of wav... Q. For air with wave... Q. Two antennas A and B radiate electromagnetic waves that are in phase and have frequency f. Antenna A is 8.00 m to the left of antenna  B and point ... Q. An oil film (n=1.45) is floating on water (n=1.33) as shown. This destructive interference occurs because a) the two beams travel distances that are different by hal... Q. The oil film is 280 nm thick. Q. all the reflected light destructively interferes), then conservation of energy requires that all of the light passes through the film to the other side.
