Question

Which of the following experimental set-ups used in the lab will produce linearly polarized electromagnetic wave (more than one answer may be correct)?

A film polarizer and then a piece of wax paper placed in front of initially un polarized light. Three film polarizers placed in front of initially unpolarized light oriented at any angles. hree film polarizers placed in front of initially unpolarized light oriented at any angles, as long as all three angles are less than 90 degrees. A wire grid placed parallel to the orientation of initially polarized microwave. wo film polarizers placed in front of initially unpolarized light with relative angle between the polarizers equal 90 degrees. Initially unpolarized light scattered along the direction of propagation of the original light. Two film polarizers placed in front of initially unpolarized light with relative angle between the polarizers less that 90 degrees. A wire grid placed perpendicularly to the orientation of initially polarized microwave.

Answer 1

A film polarizer and then a piece of wax paper placed in front of initially unpolarized light.

It is the right answer......
