Atoms And Nuclei Question 89

Question: If λmax is 6563 Å, then wave length of second line for Balmer series will be [RPMT 2000]

Options:

A) λ=163R

B) λ=365R

C) λ=43R

D) None of the above

Show Answer

Answer:

Correct Answer: A

Solution:

For Balmer series 1λ=R(1221n2) where n = 3, 4, 5

For second line n = 4

So 1λ=R(122142)=316Rλ=163R
