Height of a water tank is 4.8 m. The tank is full with water has a refractive index = 1.33. The tank's top with water is exposed to some air. A technician installed a light bulb at the bottom of tank and positioned the lightbulb head so that the light doesn't exit the water. To fullfil this task, where does the light need to strike on the air-water interface, relative to the spot directly above the bulb installed location. (Please draw and include a figure with all the incident and reflected rays of the light & write out all the appropriate angles)
