You are working for a solar energy company. Your supervisor has asked you to investigate a new idea that has been proposed for a solar collector. A large sphere of glass focuses light on photocells, as shown in Figure P35.22. The photocells are moved by electronics along the curved track to the right of the sphere. Your supervisor would like to build a prototype of a material with index of refraction n, but needs for you to calculate the position at which the Sun’s rays focus and, therefore, to find where to locale the curved track.

- Consider a light ray that enters a pane of glass with air on one side and water on the other side as shown in Figure P38.21. The light ray experiences refraction at the first interface when it enters the glass from the water and again at the second interface when it exits the glass into the air. Assume the index of refraction of the glass is 1.54. For a ray of light, find the angle of incidence 1 in the water such that the ray experiences total internal reflection when it strikes the glassair interface on the other side. FIGURE P38.21arrow_forwardQ1/ Consider a laser cavity consisting of a concave mirror and a convex mirror, separated by 2m as shown in the figure. . Given R1=R2 = 2m, where R1 and R2 are the radii of curvatures of the concave and convex mirrors, respectively. Obtain the matrix representing the ray transformation for one complete round trip in the cavity?arrow_forwardStudents in a lab group are given a plastic cube with a hollow cube-shaped space in the middle that fills about half the volume of the cube. The index of refraction of the plastic is known. The hollow space is filled with a gas, and the students are asked to collect the data needed to find the index of refraction of the gas. What information would you need to collect, and how would you use this information in order to deduce the index of refraction of the gas in the cube?arrow_forward
- When the light illustrated in Figure P35.21 passes through the glass block, it is shifted laterally by the distance d. Find the time interval required for the light to pass through the glass block, where t = 1.50 cm, n = 1.50, and = 35.0⁰ ps Figure P35.21arrow_forward34. Consider a beam of light from the left entering a prism of apex angle O as shown in Figure P34.34. Two angles of incidence, 0, and 0,, are shown as well as two angles of refraction, 0, and 0,. Show that O = 0, + 0g- 2 %D 2 3°arrow_forwardA drop of water (n=1.33) in the shape of a hemisphere with radius 3.0 mm sits on smooth horizontal surface of a sapphire (n=1.77). A thin laser beam enters the droplet from air and reaches the water-sapphire boundary at the exact center of their circle of contact. At that point, laser beam is completely reflected off the surface of the sapphire. a. What is the maximum height above the sapphire that the laser beam could enter the droplet to be internally reflected at the center of the droplet as described above? b. What is the angle of incidence as the beam enters the droplet?arrow_forward
- Light is incident on a prism as shown in Figure P38.31. The prism, an equilateral triangle, is made of plastic with an index of refraction of 1.46 for red light and 1.49 for blue light. Assume the apex angle of the prism is 60.00. a. Sketch the approximate paths of the rays for red and blue light as they travel through and then exit the prism. b. Determine the measure of dispersion, the angle between the red and blue rays that exit the prism.
