A 1.0 cm thick layer of an unknown liquid floats on top of a pool of water. Sunlight strikes the surface of the unknown liquid at an angle of 65" above the surface of the liquid. What is the light's direction of travel through the water? You notice later in the day that right when the sunlight strikes the unknown liquid at an angle of 24° above the surface of the liquid there is total interanl reflection of the light at the boundary between the unknown liquid and the water. Also, you determine that the light strikes the water a horizontal distance of 5.0 cm from where the light initially strikes the unknown liquid. See the attached figure. What is the index of refraction of the unknown liquid? Please give the direction of travel of the light in Blackboard, and include the answers to both questions in your written work. 1.0 cm 24° 5.0 cm Air Liquid Water
