    Consider the following two statements :
    (A) Line spectra contain information about atoms.
    (B) Band spectra contain information about molecules.
    (a) Both A and B are wrong
    (b) A is correct but B is wrong
    (c) B is correct but A is wrong
    (d) Both A and B are correct
    digAnsr:   d
    Ans : (d) Both A and B are correct.
    Because line spectra contain wavelengths that are absorbed by atoms and band spectra contain bunch wavelengths that are absorbed by molecules, both statements are correct.
