When white light illuminates a thin film normal to the surface, it strongly reflects both blue light (500 nm in air) and red light (700 nm in air) as shown in the figure below. White light Blue and red are reflected Air Film Water 1) Calculate the minimum thickness of the film if it has an index of refraction of 1.35 and it "floats" on water with n = 1.33. (Express your answer to two significant figures.) 135 nm Submit

A uniform film of TiO2, 1036 nm thick and having index of refraction 2.62, is spread uniformly over the surface of crown glass of refractive index 1.52. Light of wavelength 600 nm falls at normal incidence onto the film from air. You want to increase the thickness of this film so that the reflected light cancels. What is the minimum thickness of TiO2 that you must add so the reflected light cancels as desired? After you make the adjustment in...

The reflection of light from the thin film of thickness t as
shown in the figure appears violet (400nm) when viewed from above.
This means the two rays reflecting off of the two surfaces
interfere constructively. t is the minimum thickness. The dark grey
material has a higher index of refraction than the light grey with
the white being air. For what minimum thickness relative to t would
it need to be for the film to now appear red (700nm)...

IP A thin soap film (n = 1.33) suspended in air has a uniform thickness. When white light strikes the film at normal incidence, violet light ( λV = 420 nm) is constructively reflected. A) If we would like green light ( λG = 560 nm) to be constructively reflected, instead, should the film's thickness be increased or decreased? Answer: A thickness of the film must be increased OR B thickness of the film must be decreased B) Find the...

A soap film (n=1.33) is 781 nm thick. White light strikes the film at normal incidence. You may want to review (Pages 991 - 997) . Part A What visible wavelengths will be constructively reflected if the film is surrounded by air on both sides? If there is more than one answer, separate them by a comma.

(a) Briefly explain what is meant by the following terms: refraction, refractive index, angle of incidence, angle of refraction. [4 marks] (b) The drawing shows four different situations in which a light ray is traveling from one medium into another. In some of the cases, the refraction is not shown correctly. For cases (i), (ii), and (iii), the angle of incidence is 55°; for case (iv), the angle of incidence is 0°. Identify which cases are incorrectly drawn and determine...

Newton's Ring Experiment a. Newton's rings are formed with reflected light of wavelength 5890x 10-10 m using a plano-convex lens and a plane glass plate with liquid between them. The diameter of the third bright ring is 2 mm. If the radius of curvature of the curved surface of the lens is 90 cm find the refractive index of the liquid. b. The diameter of the tenth dark ring in a Newton's ring system viewed normally by reflected light of...
