Homework Statement
You have a light bulb where the filament (in vacuum space) starts to glow. This light hits the glass of the bulb at 90 degrees from distance R and is transmitted through the glass of thickness s into the air, of index of refraction nair.
So light travels like this: vacuum -> glass (thickness s) -> air.
How do you find the intensity of light transmitted?
Answer should be in terms of the absorption coefficient α, nair, R, thickness s, and Iο. Index of refraction of a vacuum is 1.
Homework Equations
Beer Lambert's law?
Fresnel's Equations?
The Attempt at a Solution
I tried using Fresnel's equations but couldn't incorporate thickness s , R, and the absorption coefficient α.
