Question

Use the exact values you enter to make later calculations A ray of light strikes a flat, 2.00-cm-thick block of glass (n-1.67) at an angle of θ-40.0° with respect to the normal (see figure below). 2.00 cm (a) Find the angle of refraction at the top surface and the angle of incidence at the bottom surface. 6 638 Your response differs from the correct answer by more than 10%. Double check your calculations. (b) Find the refracted angle at the bottom surface 40.00 (c) Find the lateral distance d by which the light beam is shifted. 0 84412 Your response differs from the correct answer by more than 10%. Double check your calculations. cm (d) Calculate the speed of light in the glass. 1798268m/s (e) Calculate the time required for the light to pass through the glass block. 1207 1e-10 レ s (0 Is the travel time through the block affected by the angle of incidence? O No O Yes, a slightly larger angle will decrease the travel time O Yes, a slightly larger angle will Increase the travel time. Need Help? I ma"
