4 glass tube with an internal diameter of d = 50 cm and wall thickness of t = 5 cm is filled with chemical liquid. When a He-Ne laser light beam perpendicularly passes through this glass tube, the exit light energy (intensity) decreases by half (I, =I.). Assume that the coefficient of absorption of the glass is 2aG = 0.01 cm-1. Compute the coefficient of absorption of the liquid inside the tube
