Product description
A pile is driven vertically into the bottom of the reservoir. The length of the underwater part of the pile is k=2 times greater than the surface part. Assuming the bottom of the reservoir is horizontal, determine how many times the length of the part of the pile rising above the bottom of the reservoir is greater than the length of its shadow at the bottom of the reservoir. The falling rays of the sun form an angle a=60° with the surface of the water. The refractive index of water is n=1.33.
