Challenge Problems
Push your limits with challenges.
Question 1
If you have unpolarized light with an intensity of 200 units passing through a single polarizer, what will be the transmitted intensity? If a second polarizer is then added at an angle of 45 degrees from the first, what will be the output intensity?
💡 Hint: Remember to halve the intensity first and then apply the angle for the second polaroid.
Question 2
Explain how to configure two polarizers to achieve maximum light transmission and provide a scenario where this could be useful.
💡 Hint: Think about how you control light in different mediums.
