Part 1: The index of refraction of a transparent liquid (similar to water but with a different index of refraction) is 1.52. A flashlight held under the transparent liquid shines out of the transparent liquid in a swimming pool. This beam of light exiting the surface of the transparent liquid makes an angle of θa = 33 ◦ with respect to the vertical. At what angle (with respect to the vertical) is the flashlight being held under transparent liquid? Answer in units of ◦ .
