Question

Light is entering a polarizer or set of polarizers from the left. Determine the relative intensity of the light exiting on the right after passing through all of the polarizers. The dashed vertical lines represent the vertical reference. The solid lines represent either the polarization angle of the light or the transmission angle of the polarizer. CW represents clockwise and CCW represents counterclockwise as viewed from the right looking back to the left along the path of the light.

ANSWER AS: Full Intensity, Partial Intensity, or Zero Intensity

A) Unpolarized light enters from the left and passes through one polarizer with the transmission axis oriented 45

Light is entering a polarizer or set of polarizers from the left. Determine the relative intensity of the light exiting on the right after passing through all of the polarizers. The dashed vertical lines represent the vertical reference. The solid lines represent either the polarization angle of the light or the transmission angle of the polarizer. CW represents clockwise and CCW represents counterclockwise as viewed from the right looking back to the left along the path of the light. ANSWER AS: Full Intensity, Partial Intensity, or Zero Intensity A) Unpolarized light enters from the left and passes through one polarizer with the transmission axis oriented 45 A degree CW relative to the vertical and then through a second polarizer with the transmission axis oriented 45° CW relative to the vertical. Light is entering a polarizer or set of polarizers Light is entering a polarizer or set of polarizers E) Unpolarized light enters from the left and passes through a single polarizer with the transmission axis oriented vertically (0 A degree relative to the vertical). Light is entering a polarizer or set of polarizers D) Linearly polarized light with the plane of polarization horizontal enters from the left and passes through a single polarizer with the transmission axis oriented vertically (0 A degree relative to the vertical). Light is entering a polarizer or set of polarizers C) Unpolarized light enters from the left and passes through a single polarizer with the transmission axis oriented horizontally (90 A degree relative to the vertical). Light is entering a polarizer or set of polarizers B) Unpolarized light enters from the left and passes through a single polarizer with the transmission axis oriented horizontally (90 A degree relative to the vertical).

Explanation / Answer

Here ,

A)

Here , as as the light passes thorugh the first polarizer ,

it's intensity decreses to half, as the second polarizer is at the same angle as the first , the intensity here is unchanged.

But overall the intensity is PARTIAL Intensity

B)

as as the light passes thorugh polarizer ,

it's intensity decreses to half , Hence , Partial intensity

C)

as as the light passes thorugh polarizer ,

it's intensity decreses to half , Hence , Partial intensity

D)

Here ,as the angle between the polarization and axis of polarizer is 90 degree

the outpout Intensity = Io* (cos (90))^2 = 0

Hence , Zero Intensity

E)

as as the light passes thorugh polarizer ,

it's intensity decreses to half , Hence , Partial intensity
