Task 40913.
Two protective layer of uniform thickness weaken the intensity of the beam of monochromatic rays. The first layer attenuates the intensity of the rays at twice the absorption coefficient of 0.05 m ^ -1. The second layer attenuates the intensity five times. What is the coefficient of linear absorption of this layer?
