  1. Refraction 1 In the image below, light refracts from material #2 to material #3. The reflected ray is not shown. Which is true? n3>n2 n3<n2 n3=n2 this refraction is impossible

  2. Refraction 2 In the image below, light refracts from material #2 to material #3. The reflected ray is not shown. Which is true? n3>n2 n3<n2 n3=n2 this refraction is impossible

  3. Refraction 3 The incident ray (shown gray in the figure) consists of red and blue light. The approximate index of refraction is indicated for each material, but the index of refraction in the second material is slightly larger for blue light than for red light, so they refract in slightly different directions. Which of the three images shows a physically possible refraction? none

  4. Refraction and Appearances Light changes direction when it refracts we see images where light appears to come from In the image below, the circle at the bottom represents the actual object; the dashed line represents the direction where it looked like the light was coming from. Draw the actual ray of light… draw and label the incident ray from the object under the water and the refracted ray in the air (to observer’s eye)

  5. Refraction Calculation • If the light from the object reaches the surface of the water at an angle of 25o with vertical, • what is the angle of incidence? 25o • what is the angle of refraction? 34o • What happens if you try to repeat part 2 for an angle of 55o with vertical? mathematics gives error – ray does not refract, just reflects
