Answer to relevant QuestionsThe photos in Fig. 22.24 were taken with a camera on a tripod at a fixed angle. There is a penny in the container, but only its tip is seen initially. However, when water is added, more of the coin is seen. Why? Use a ...Light passes from a crown glass container into water. (a) Will the angle of refraction be (1) greater than, (2) equal to, or (3) less than the angle of incidence? Explain. (b) If the angle of refraction is 20o, what is the ...Light passes from material A, which has an index of refraction of 4/3, into material B, which has an index of refraction of 5/4.
