The explanation for this seeming paradox is that light from the sun bends slightly when entering the earth’s atmosphere, as shown in Fig. Since our perception is based on the idea that light travels in straight lines, we perceive the light to be coming from an apparent position that is an angle d above the sun’s true position. (a) Make the simplifying assumptions that the atmosphere has uniform density, and hence uniform index of refraction n, and extends to a height h above the earth’s surface, at which point it abruptly stops. Show that the angle d is given by as attached. where R = 6378 km is the radius of the earth. (b) Calculate d using n = 1.0003 and h = 20 km. How does this compare to the angular radius of the sun, which is about one quarter of a degree?

She is explaining to her friend how she can see the book cover as blue. She said: "I can see the book cover as blue because light from the sun travels in straight lines to the book. The white light from the sun contains red, green, and blue light. When it strikes the book cover, the blue light is reflected at equal angles, while the rest of the colors are absorbed in the book cover. The reflected blue light then enters my eye, and I see the book cover as blue." Evaluate her explanation to determine whether it is good or poor, by choosing one of the following responses: O It is problematic because the idea that "the white light from the sun contains red, green, and blue," is not correct. It is problematic because the idea that "mostly the blue light energies are reflected at equal angles," is not correct. It is good because all the ideas are correct scientific ideas, and none of the important ideas are…arrow_forward
