is the frequency of the balmer series

Answer 2

Answer:

frequency = 8.22×10^14 per second

Explanation:

The limiting line for the Balmer series means infinite orbit to 2nd orbit transition. 

We know ,

1/λ=R(1/n1^2−1/n2^2)    

  

1/λ=R(1/2^2−1/M^2), Here M= infinite

λ=4/R

c=λf

f=cR/4

f=3×108×1.09677×10^7/4

=8.22×10^14sec−1
