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