Physics Question on Atoms and Nuclei
The shortest wavelengths emitted in the hydrogen spectrum corresponding to different spectral series are:
(A) Pfund series
(B) Balmer series
(C) Brackett series
(D) Lyman series.
The wavelengths arranged correctly in decreasing order are_______.
Fill in the blank with the correct answer from the options given below.
A
(A), (B), (C), (D)
B
(A), (C), (B), (D)
C
(B), (A), (D), (C)
D
(A), (C), (D), (B)
Answer
(A), (C), (B), (D)
Explanation
Solution
The Lyman series emits the shortest wavelength, followed by Balmer, Brackett, and Pfund. Hence, the correct order is (D), (C), (B), (A), making Option 2 correct.
