Introduction to Engineering Materials Question:

A beam of light hits a 2.48cm thick silicate glass plate at an angle of 74 degrees (as measured from the normal to the surface of the glass). If the coefficient of linear absorption is 0.027 cm-1 and the index of refraction is 1.488, what fraction of light is passed through the plate. The answer should have three decimals of accuracy.

The answer is: 0.847, I need to know the process.
