Consider the following statements about the hydrogen spectrum.
(I) The Lyman series lies in the ultraviolet region.
(II) The first line of the Balmer series has a longer wavelength than the second line.
(III) The shortest wavelength of the Paschen series corresponds to the 4 to 3 transition.
(IV) The Balmer series is the only series of hydrogen that lies in the visible region.
Which of the statements are correct?
Options:
Answer:
B
Solution:
(I) True. (II) 3 to 2 has less energy than 4 to 2, so a longer wavelength: true. (III) False: the shortest wavelength is the series limit, and 4 to 3 is the longest. (IV) True.
Answer: (B).
