Sunlight with an angle of incident of 30 degrees hits a thin oil layer, floating on a puddle of water. The oil layer is 185nm thick and has an index of refraction of 1.49, the water has an index of 1.33 and is 2mm thick. a) There is a dominant reflection of this light at what wavelength? [b) What colour would this reflection appear? c) Describe in 20 words or less the polarization of the reflected light: use at least 3 from the list here to describe the polarization of this reflection: polarized, linear, vertical, horizontal, right-handed, left-handed, elliptical, circular, unpolarized, partially polarized

puddle of water has an oily thin film floating on it. A beam of light is shining perpendicular on the film. If the wavelength of light incident on the film is 532 nm and the indices of refraction of the oil and water are 1.40 and 1.33, respectively, what must be the minimum thickness of the film to see a bright reflection?

Due to an unwanted oil spill, a thin film of oil of refractive index 1.40 floats on water (refractive index 1.33). When sunlight is incident at right angles to this film, the only colors that are absent from the reflected light are blue (458nm) and red (687nm). (a) Draw a diagram showing the reflected rays for either blue or red. (b)Estimate the thickness of the oil film. (c)If the only colors enhanced by reflection were blue and red, what would...

1) 2 point charges are separated by a distance of 8 cm. The left charge is 48 mC and the right charge is -16mC. Using a full sheet of paper: draw the 2 charges separated by 8cm, centered in the sheet. (if you are missing a ruler estimate 8cm as ⅓ a paper sheet length). [6] a) Draw field lines to indicate the electric fields for this distribution. [4] b) Draw 3 equipotential surfaces, 1 each, that pass: -Through the...
