The drawing shows four different situations in which a light ray is traveling from one medium into another. In some of the cases, the refraction is not shown correctly. For cases (a), (b), and (c), the angle of incidence is 55; for case (d ), the angle of incidence is 0. Determine the angle of refraction in each case. If the drawing shows the refraction incorrectly, explain why it is incorrect.
Slide 25 Slide 26 -I will get smaller and smaller -What is delta V for one small piece Slide 27 Slide 28 Slide 29 Slide 30 -an angle is made because they are not parallel -no potential difference -PD does NOT depend on angle of path! This is because PD doesn’t change al
