An unpolarized light beam with intensity I0 is first passed through an ideal polarizer. At this instant, the light is polarized. We then pass that light through 3 more identical polarizers having parallel axes of transmission to each other. If the transmission axis of the final polarizer makes an angle of 45 ∘∘ with the electric field direction of the polarized light, what is the intensity of the emerging light?

The intensity of the emerging light reduced to 25%

Explanation:

Given :

Unpolarized light intensity =

Initial polarizer angle = 0°

Final polarizer angle between optic axis and transmission axis = 45°

Unpolarized light passes through first polarizer the intensity reduces to half.

after second polarizer the intensity is half till the last polarizer,

Therefore, the intensity of the emerging light reduced to 25%

force tends to be low and long diustance masses are high

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
