An opaque cylindrical tank with an open top has a diameter of 3m and is completely filled with water. When the afternoon sun reaches an angle of 28o above the horizon, sunlight cease to illuminate and part of the bottom of the tank. How deep is the tank?
I don't understand how to approach this question but more importantly I guess I should ask why doesn't the bottom part of the tank is not illuminated?
