Atoms And Nuclei Question 445

Question: If λmax is 6563 Ao, , then wave length of second line for Balmer series will be

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)

1λ=R122142 where n = 3, 4, 5 For second line n = 4

So 1λ=R(122142)

=316Rλ=163R
