Task 40051.
The intensity of light of two different waves λ1 and λ2 is measured directly in the liquid at the surface and at depth d. It was found, I01 = I02 at the surface and at depth d Id1 = 2Id2. To determine the depth at which the light intensity exceeds the wavelengths λ1 light intensity wavelength λ2 by 10 times.
