Question
Looking at the polarize filters below - state how bright the light would be compared to totally unpolarized light shining (represented by the star) through the polarizers. Make sure to state through each polarizer (where the?? are in the image.) If a diffraction grating behaves in a similar fashion as a prism with respect the white light shining through the grading, state why the experiment you will conduct to observe diffraction uses a single band a red light rather than a white light source. (For diffraction - you will be measuring the distance between bright spots on a screen representing construction interference -where two waves of light are additive and thus the point is brighter than other spots on the screen.)Explanation / Answer
Intentisy of the light after first polarizer I ' = I / 2
Where I = Intensity of the unpolarized light
Intensity of the light after second polarizer is zero.
Since first and second polarizers are in 90 o
According to Malus law Intensity of the light after second polarizer I " = I ' cos 2 90
cos 90 = 0
So, I " = 0
(2) If you use white light then the principal maximum is in white color.remianing maxima's are different colors rather than white.
