SUMMARY
The discussion focuses on calculating the depth of an opaque cylindrical tank filled with water, which has a diameter of 3 meters. When sunlight reaches an angle of 28 degrees above the horizon, it fails to illuminate part of the tank's bottom. Participants suggest using trigonometric principles, specifically the sine or cosine rule, to determine the tank's height, concluding that the depth is approximately 1.41 meters. The reasoning behind the lack of illumination at the bottom is attributed to the low angle of sunlight during the afternoon.
