(A) 27/5 λ
(B) 5/27 λ
(C) 9/2 λ
(D) 2/5 λ

Answer 1

Answer:

1. A)5/27lambda
2. I feel like that is answer of this question

Answer 2

Answer:

a) 27/5 λ

Explanation:

The Balmer series is a series of the hydrogen atom spectral emission lines which result from the electron transitions from high levels down to the energy level having the principal quantum number as two.

For the first line in Lyman series  = λ L 1  =  4/ 3 R  --- 1

For the first line in Balmer series  = λ B 1  =  36/ 5 R  --- 2

Therefore, from equation 1 and 2

λ B 1/ λ L 1   = 36/ 5 R / 4/ 3 R  

λ B 1 = 27/5λ L 1

λ B 1 = 27/5λ

Therefore, the wavelength of the first line in Balmer series is 27/5 λ.
