1.	Assertion : If the light from an ordinary source passes through a polaroid sheet, its intensity is reduced by half. Reason : The electric vectors associated with the light wave along the direction of the aligned molecules get absorbed by polaroid.A. If both assertion and reason are true and reason is the correct explanation of assertion.B. If both assertion and reason are true but reason is not the correct explanation of assertion.C. If assertion is true but reason is false.D. If both assertion and reason are false.
Answer» Correct Answer - A A polaroid consists of long chain molecules aligned in a particular direction. The electric vectors associated with the propagating light wave along the direction of the aligned molecules get absorbed. Thus if the light from an ordinary source passes through a polaroid sheet, its intensity get reduced by half.
