- Table P35.80 presents data gathered by students performing a double-slit experiment. The distance between the slits is 0.0700 mm, and the distance to the screen is 2.50 m. The intensity of the central maximum is 6.50 106 W/m2. What is the intensity at y = 0.500 cm? TABLE P35.80arrow_forwardQ3/A/We wish to coat a glass surface with an appropriate dielectric layer to provide total transmission from air to the glass at a free-space wavelength of 570 nm. The glass has refractive index n3 = 1.45 . Determine the required index for the coating and its minimum thickness.arrow_forwardThe pupil of an eagle's eye has a diameter of 6.0 mm. Two field mice are separated by 0.010 m. From a distance of 197 m, the eagle sees them as one unresolved object and dives toward them at a speed of 20 m/s. Assume that the eagle's eye detects light that has a wavelength of 550 nm in vacuum. How much time passes until the eagle sees the mice as separate objects? t= iarrow_forward
- You are conducting a single-slit diffraction experiment with light of wavelength l. What appears, on a distant viewing screen, at a point at which the top and bottom rays through the slit have a path length difference equal to (a) 5l and (b) 4.5l?arrow_forwardAn investigator finds a fiber at a crime scene that he wishes to use as evidence against a suspect. He gives the fiber to a technician to test the properties of the fiber. To measure the diameter of the fiber, the technician places it between two flat glass plates at their ends as in Figure P24.24. When the plates, of length 14.0 cm, are illuminated from above with light of wavelength 6.50 x 102 nm, she observes bright interference bands separated by 0.580 mm. What is the diameter of the fiber?arrow_forwardYour friend has been given a laser for her birthday. Unfortunately, she did not receive a manual with it and so she doesn't know the wavelength that it emits. You help her by performing a double-slit experiment, with slits separated by 0.36 mm. You find that the two m=1 bright fringes are 5.5 mm apart on a screen 1.6 mm from the slits. What is the wavelength the laser emits?arrow_forward
- Q3/A/We wish to coat a glass surface with an appropriate dielectric layer to provide total transmission from air to the glass at a free-space wavelength of 570 nm. The glass has refractive index n, = 1.45. Determine the required index for the coating and its minimum thickness.arrow_forwardYou are working in an optical research laboratory. One of your projects involves the use of a double slit through which you pass orange laser light of wavelength 590 nm. Unfortunately, because of budget cuts, there are a lot of researchers in the same room, with lots of equipment stuffed in theroom, and, in particular, lots of laser beams flying around the room. One day, you find that a second laser beam of unknown origin and different color is entering your double slit along with your orange beam and you are seeing an interference pattern that is the sum of those due to the twobeams. You notice that the combined pattern is pretty much a mess, but wait! The m = 3 maximum of your orange laser beam pattern is pure; there is absolutely no mixture of the other color at that point. From this fact, you determine the wavelength of the offending laser light so that you can figure out which other researcher to ask to modify the aiming of his laser.arrow_forwardAnti-reflective coatings on camera lenses and glasses work by utilizing thin-film interference to greatly reduce reflected light. (Ever wondered why your glasses have a bluish/magenta tint when they reflect light? It's from that thin film!)We wish to coat flat glass (n=1.50) with a transparent material (n=1.25), so that reflection of light at wavelength 402.375nm is eliminated by interference. What is the minimum thickness (nm) of the coating that will work for our purposes?arrow_forward
- Light of wavelength 580 nm falls on a calcite crystal of certain thickness. The emerging light is circularly polarized. What must be the thickness of such crystal?arrow_forwardThe Michelson interferometer can be used to measure the index of refraction of a gas by placing an evacuated transparent tube in the light path along one arm of the device. Fringe shifts occur as the gas is slowly added to the tube. Assume 580-nm light is used, the tube is 5.40 cm long, and 152 fringe shifts occur as the pressure of the gas in the tube increases to atmospheric pressure. What is the index of refraction of the gas? Hint: The fringe shifts occur because the wavelength of the light changes inside the gas-filled tube. (Give your answer to five decimal places.) 4.0arrow_forwardMonochromatic light (l = 500 nm) is incident on a soap bubble (n = 1.40). What is the wavelength of the light (in nm) in the bubble film?arrow_forward
