(Solution) - A beam of monochromatic light passes through a pile of N 5 -(2025 Original AI-Free Solution)
Paper Details
A beam of monochromatic light passes through a pile of N = 5 identical plane-parallel glass plates each of thickness 1 = 0.50 cm. The coefficient of reflection at each surface of the plates is p = 0.050. The ratio of the intensity of light transmitted through the pile of plates to the intensity of incident light is ? = 0.55. Neglecting the secondary reflections of light, find the absorption coefficient of the given glass.
