Question

Problem 23.59:

A beam of unpolarized light of intensity I0 passes through a series of ideal polarizing filters with their polarizing directions turned to various angles as shown in the figure (Figure 1) . Assume that ? = 35.0 ?.

Part A

What is the light intensity (in terms of I0) at points A, B, and C?

Answer in the order indicated. Separate your answers with commas.

Part B

If we remove the middle filter, what will be the light intensity at point C?

Problem 23.59 Part A A beam of unpolarized light of intensity Io passes through a series of ideal polarizing filters with their polarizing directions turned to various angles as shown in the figure (Figure 1).

Explanation / Answer

Here

part A)

as the light is unploarized initially

IA/Io = 0.5

Now , at point B

IB/To = cos(35)^2

IB/Io = 0.671 * 0.5

IB/Io = 0.336

at point C

IC/Io = 0.336 * cos(90 - 35)^2

IC/Io = 0.1103

part B)

Now , if the middle filter is removed

IC' = Io * cos(90)^2

IC' = 0 W/m^2
