2 2 points A glass of height 16.0 cm and diameter 8.00 cm is completely filled with an unknown liquid. A coin is placed in the exact center of the cup. See the figure. Light reflecting off the coin follows the path out into the air as is shown by the purple line. The light ray that goes into the air is headed directly away from the lower right side of the cup, as depicted by the black dashed line. 16.0 cm 8.0 cm > What is the index of refraction of the unknown liquid? Assume air has an index of refraction of 1.00 Type your answer...
