Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

this is actually working of wave grid polarizer..For wire grid polarizer are made of fine metal wire and that are usually 100 nm to several microns..Its work depending on wave length range.. actually as it restrict s component of ELECTRIC FIELD, so its range should be less than wave length ..So that it could restrict s component... please check the attached picture
