Textbook Question

Chapter 11.7, Problem 1bT

Hold a second polarizing filter in front of the first, and look at the room lights again.

Describe how the filter affects the light that you see. How does rotating one of the filters with respect to the other affect what you see?

On the basis of your observations, why is it appropriate to use the term filler to describe these piece of apparatus?

How is the behavior of the polarizing filter different from the behavior of colored acetate filters?

Chapter 11.7, Problem 1bT, Hold a second polarizing filter in front of the first, and look at the room lights again. Describe
You have learned that Light may be thought of as a wave consisting of oscillating electric and magnetic fields. If the electric field in all parts of a light beam oscillates along a single axis, the light beam is said to be linearly polarized, or simply, polarized. For example, the diagram at right represents a polarized light wave moving in the x-direction in which the electric field oscillates only along the y-axis. By convention, the direction along which the electric field oscillates (in this case, the y-direction) is called the direction of polarization of a light beam. If the electric field oscillates in different, random directions within the same light beam, that beam is said to be unpolarized.

Unpolarized light with an intensity Io passes through a linear polarizer. It then passes through a second linear polarizer that is oriented at a 72.5 degree angle with it's axis of polarization. What is the final intensity of this beam? Need to finish! Show the algebraic form of the equation(s) that you apply and express your answer in terms of the initial intensity of the beam.

Hi! Please read everything first before answering. Read carefully as well because you might be confused.I asked this question already here in Bartleby but I have not received the exact answer The question is:Unpolarized light with intensity I₀ is incident on two polarizers as sketched in Figure B. Suppose the angle between the axes of the two polarizers is θ = 60°. What is the intensity of the transmitted light? EXPRESS YOUR ANSWER AS A FRACTION OF I₀. And I got the answer 0.125 I₀. The question says THE ANSWER SHOULD BE EXPRESSED AS A FRACTION OF I₀. The answer I got is decimal and i don't know how i will turn it to fraction. I am not sure if converting it to fraction is correct so I am seeking for your help. Please help me. What I just need is TO EXPRESS MY ANSWER AS A FRACTION OF I₀. Thank you!

Suppose you have unpolarized light incident on polarizer A. Polarizer B is placed after polarizer A, so that no light passes through polarizer B. Where would you place a third polarizer (polarizer C), and how would you orient it relative to polarizer A, so that some light does pass through polarizer B?
