1.	Assertion (A) : The flim which appears bright in reflected system will appear dark in the transmitted system and vice-versa. Reason (R ) : The condittions for film to appear bright of dark in the reflected light are just revese to those in the transmitted lightA. A is true and R is true and R is the correct explanation of A.B. A and R are true but R is not correct explanation of AC. A is true, R is falseD. A is false, R is true.
Answer» Correct Answer - A For reflected system of the film, the condition for maxima is `2mu t cos r = (2n-1)lambda//2` . While the maxima for transmitted system of film is `2 mut cos r = n lambda` and is reverse for minima. A & R are true and R is the correct explanation of A
