Product description
- The light beam passes sequentially through two nicolas, the transmission planes of which form an angle φ = 40 °. Assuming that the absorption coefficient k of each nicol is 0.15, find how many times the beam of light leaving the second nicol is weakened compared to the beam incident on the first nicol.
