- A laser beam is incident on a 45°-45°-90° prism perpendicular to one of its faces, as shown in the figure below. The transmitted beam that exits the hypotenuse of the prism makes an angle of 0 = 19.5° with the direction of the incident beam. Find the index of refraction of the prism. 45.0°A laser beam shines along the surface of a block of transparent material (see figure below). Half of the beam goes straight to a detector, while the other half travels through the block and then hits the detector. The time delay between the arrival of the two light beams at the detector is 6.25 ns. What is the index of refraction of this material?The figure below shows the path of a beam of light through several layers with different indices of refraction. (Assume n = 1.02.) e₁ n = 1.60 02 n = 1.40 n = 1.20 MA (a) If ₁ = 28.0°, what is the angle 2 of the emerging beam? o 1 (b) What is the smallest incident angle ₁ to have total internal reflection at the surface between the medium with n = 1.20 and the medium with Па = 1.02?
- The index of refraction for material 1 is 1.36; for material 2 it is 1.66. Light travels 1.5 m in the first material before hitting the second material, where it travels another 1.5 m. What is the total time taken for the light to travel the total distance? Speed of light c = 2.998 x 108 m/s Total time in the two materials = = 1.51 S Reflect on the order of magntitude of this time. Is this a perceptible time delay? ! No, that's not the correct answer.You are working for an electronics company that designs and manufactures digital drives and players. Your supervisor wishes to evaluate the feasibility of using shorter-wavelength lasers than those used in Blu-ray Discs (405 nm) to try to begin a new video revolution with Ultraviolet-ray discs. as shown the general idea behind digital reading of CDs, DVDs, and Blu-ray Discs. The information is coded digitally in a plastic substrate of index of refraction 1.78 (green as shown). as shown areas called flats, which are undisturbed portions of the substrate, and pits, which are depressions in the substrate that represent the digital information. The surface of the substrate is covered with a protective reflective coating (as shown) to protect the surface from scratches. As the disc rotates, the laser beam, shown in violet coming in from below the disc, passes over a track of flats and pits. When there is a change from a flat to a pit or vice versa, part of the laser beam reflects from the…X rays are typically used to kill off cancer cells, however an issue some radiologists run into is the damage an x-ray may do to surrounding tissue. Because of this, accuracy plays a key role in radiation therapy. Suppose you are a medical physicist, and you have been given the task of choosing a medium with a proper index of refraction to bend the x rays such that they only hit the tumor. Suppose you know that the x ray comes in at an angle of 20 degrees with respect to the normal of your second medium. You know the tumor expands out to 5 degrees on either side of the normal what is the minimum index of refraction needed for the x ray to hit the tumor
