1.	For balmer series in the spectrum of atomic hydrogen the wave number of each line is given by `bar(V) = R[(1)/(n_(1)^(2))-(1)/(n_(2)^(2))]` where `R_(H)` is a constant and `n_(1)` and `n_(2)` are integers. Which of the following statements (s), is (are correct) 1. As wave length decreases the lines in the series converge 2. The integer `n_(1)` is equal to 2. 3. The ionisation energy of hydrogen can be calculated from the wave numbers of three lines. 4. The line of shortest wavelength corresponds to = 3.A. 1, 2 and 3B. 2 , 3 and 4C. 1,2 and 4D. 2 and 4 only
Answer» Correct Answer - C (1)Beyond a certain wavelength the line spectrum becomes band spectrum. (2)For Balmer series `n_1=2` (4)The line of longest wavelength in this series , `n_2=3`
