If the series limit wavelength of Lyman series for the hydrogen atom is 912 Å, then the series limit wavelength for Balmer series of hydrogen atoms is
Options
- A912 Å
- B912 2 Å
- C912 4 Å
- D912 2 Å
Correct answer
C. 912 4 Å
Step-by-step solution
1 =R [ 1 n₁² - 1 n₂² ] For limiting wavelength of Lyman series n₁=1, n₂= 1 _ L =R For limiting wavelength of Balmer series n₁=2, n₂= array l 1 _ B =R ( 1 4 ) _ B = 4 R _ B =4 _ L =4 912 array
