Answer #1

Refractive index of space is 1

Refractive index of crown glass is approximately 1.52

Since the ligth beam hits the window at an angle of 30 degrees

Angle of incidence is 60 degrees

As the refreactive indices of media are known and the angle of incidence is given we can calculate the angle of refraction using the snell's law of refraction.

Snell's law-

is the angle of refraction

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.

Snell's Law and the Law of Reflection explain how light is redirected when it encounters a surface between two media. In the extreme, light may only reflect at a boundary, and go back into the medium it was in. More often, some of it reflects and some goes through. If the boundary is plane and flat, then these laws are easy to interpret. When the boundary is curved, they describe happens at every point on the surface. One of the...
