Line by Line Explanation

Statement : wavelength of (I) line of Humphry series is more than (I) line of Lyman series in H-atom Explanation : Delta E = (hc)/( lambda) .

Assertion : The line l is parallel to the plane P. Reason: The normal of the plane P is perpendicular to the line l. (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.

Assertion: If m parallel lines are intersected by n other parallel llines, then the number of parallelograms thus formes is (mn(m-1)(n-1))/4 , Reason: A selection of 4 lines 2 form m parallel lines and 2 from n parallel lines givers one parallelogram. (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.
