Problem An extended light source can be modeled as a group of several point-like light sources. The figure below shows a linear light source (such as fluorescent lamp) modeled by three point-light sources, a sheet of black paper, and a screen. Light source Side view Paper Screen A. Copy the sketch in your notebook. Determine the regions of shadow and semi-shadow on the screen by drawing rays from the three point-like light sources. B. Qualitatively compare the relative brightness (and darkness) of the regions.

Activity; Light Facts n' Graphic Organizer Halos and sun dogs are phenomenon that is caused by refraction of light through ice crystals, while sun pillars are the reflection of the sun's rays off on ice crystals. Moreover, rainbows are caused by reflection, refraction, and dispersion of light in water droplets. Tell us more about these phenomenon. Organize your description of each of these using compare and contrast graphic organizers. Research on what appropriate graphic organizer to be used to show the similarities and difference between these phenomenon: a. halos, sundogs, sun pillars; and b. primary rainbows, secondary rainbows, supernumerary bows.
Read the following problem and solve the following questions. Show your complete solutions legibly and concisely in the space provided. A light is traveling from air into an optic fiber having an index of refraction of 1.44. a. Which direction should the light bend? b. Given a 22 degree angle of incidence on the end of the fiber, what is the angle of refraction inside the fiber? c. Make a sketch of the path of life as the media changes.
A ray of light passes from air into a block of transparent material X as shown in the diagram below. Trace the correct path of the light ray as it exits material X.
The side-view mirrors of most cars are convex spherical mirrors (so that the driver can see a wider angle behind the car). Suppose that the side view mirror of your car has a radius of curvature of 18 m, and that another car is 10 m in front of the mirror (behind the car). Ignore any aberration. a) Using the mirror equation to calculate how far the other car appears to be from the mirror. b) Sketch a light ray diagram including the object, the mirror, the image, and the principal light rays. c) Is the image distance smaller or larger than the object distance? Is the image smaller or larger than the object? Answer with calculations.
One well-known image of a prism is the following picture a. Given the pattern of light on the far side of the prism, is the index of refraction inside the prism higher or lower than the index of refraction outside the prism? b. List at least one thing that is wrong with this diagram given what we expect the dependence of n on the wavelength of light to be (and assuming the prism is made of a uniform material). c. List at least one thing that is right with this diagram given what we expect the dependence of n on the wavelength of light to be (and assuming the prism is made of a uniform material).
All answers require full explanations in complete sentences. The figure below shows a spherical bubble of CO2 gas in a liquid. The index of refraction of the liquid is 1.5 times larger than that of the gas. A light ray in the liquid is incident on the bubble as shown. The black dot identifies the center of the bubble. Draw, precisely, a reasonable ray transmitted into the bubble and explain how you why it looks as you have drawn it. determined
