Chapter 25.7, Problem 1aTH
Identical beams of light are incident on three different pairs of (ideal) polarizers. The double arrow drawn on each polarizer represents its direction of polarization.
- Suppose that the incident light in each case were unpolarized.
Rank the three cases (A−C) according to the intensity of the light transmitted past the second polarizer, from largest to smallest. If for any case no light is transmitted past the second polarizer, state that explicitly. Explain your reasoning.
Expert Solution & Answer
To determine
The ranking of intensity of light after passing through the second polarizer in each case.
Answer to Problem 1aTH
B<A=C
Explanation of Solution
Introduction:
The intensity of light passing through a polarizer depends directly on square of cosine of the angle. Smaller the angle between the two polarizer, greater will be the intensity of light passing through the second polarizer.
The angle between the two polariser is smallest in case A. hence the intensity of light is greatest in case A.
For case A and case C, the value of square of cosine of the angle between two polariser is same. Hence the intensity of light is same in case A and case C.
The angle between the two polariser is greatest in case B. hence the intensity of light is smallest in case B.
Conclusion:
Hence the intensity of light after passing through second polarizer is same in case A and case C and is greater than the intensity of light in case B.

- If you shine an ultraviolet light on the metal ball of a negatively charged electroscope (shown in Exercises 1 and 2), it will discharge. But if the electroscope is positively charged, it won’t discharge. Can you venture an explanation? 1. An electroscope is a simple device consisting of a metal ball that is attached by a conductor to two thin leaves of metal foil protected from air disturbances in a jar, as shown. When the ball is touched by a charged body, the leaves that normally hang straight down spread apart. Why? (Electroscopes ate useful not only as charge detectors but also for measuring the quantity of charge: the more charge transferred to the ball, the more the leaves diverge.)arrow_forwardWhen does light act like a wave and when does it behave like a particle?

- 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.
