- Building contractors often install double-glazed windows to prevent thermal energy (heat) from entering or exiting a building. In addition to being effective insulators, such windows present interesting optical effects. glass In the figure, a double-glazed window consists of two identical panes of glass (ng = 1.46), each yg = 12.0 mm air thick, separated by an air gap of y, = 9.60 mm. If light incident on the glass makes an angle of o = 40.00° with respect to the glass, find the shift in path Ax as the light glass enters the room. Use na = 1.00 for the index of refraction of air. Ax = mmA thin prism of 5° angle gives a deviation of 3.2°. What is the value of refractive index of the material of the prism?For 589-nm light, calculate the critical angle for the following materials surrounded by air. (a) cubic zirconia (n = 2.20) (b) gallium phosphide (n = 3.50) (c) polystyrene (n = 1.49)
- 3. If on a glass plate with refractive index 1.52, rests a soap bubble of thickness 742nm with n=1.33, what will be the colours seen on the soap bubble.Green light (wavelength=550 nm) and blue light (wavelength=450 nm) strikes a diamond (ndiamond=2.42) at an angle of 23° from the normal to the air-diamond interface. What is the difference between the angles that each of the two rays refract?2. (6 points) A predatory Angler Fish has evolved bioluminescence, so that it can make its own light that it uses like a flashlight to help see its prey. A species of jellyfish lives in deep ocean water (so that the only light that reaches it is the light produced by the angler fish). The index of refraction of water is 1.333. The body of the jellyfish is mostly water surrounded by a "thin film" of transparent cells with an index of refraction ncells = 1.19. If the body of the jellyfish is 0.5 μm thick, what color of light should the fish produce to be able to see the jellyfish? water water cells 2(1.50) (0.5X105 m) = (m+11) ~
- Light originating in air is normally incident on a thin film of thickness 150nm with index of refraction n₁ = 1.5 that lies on top of a material with index of refraction n₂ = 1.2, as illustrated. nAir n1 n2 Determine the longest wavelength of light that is maximally reflected. O 450nm O 900nm O 600nm O 300nmA flat piece of glass is held stationary and horizontal above the highly polished, flat top end of a 12.0-cm-long vertical metal rod that has its lower end rigidly fixed. The thin film of air between the rod and glass is observed to be bright by reflected light when it is illuminated by light of wavelength 490 nm. As the temperature is slowly increased by 21.5°C, the film changes from bright to dark and back to bright 200 times. What is the coefficient of linear expansion of the metal? °C-1
