A beam of light hits a 2.36cm thick silicate glass plate at an angle of 64 degrees (as measured from the normal to the surface of the glass). If the coefficient of linear absorption is 0.019 cm-1 and the index of refraction is 1.417, what fraction of light is passed through the plate. The answer should have three decimals of accuracy.
You Answered: .867 Correct Answer 0.888 You will need to calculate the actual distance the light travels in the plate, do not just use the thickness. Don't forget to include Snell's law as needed.
how did they get 0.88
