Solve the all parts of given problem;
Problem: Three polarizing filters are stacked, with the polarizing axis of the second and third filter at angles of 25.0o and 90.0o, respectively, to that of the first. If unpolarized light is incident on the stack, the light has an intensity of 50.5 W/m2 after it passes through the stack. If the incident intensity is kept constant:
Part I: What is the intensity of the incident light?
Part II: What is the intensity of the light after it has passed through the stack if the second polarizer is removed?
