Answer:
The wavelength of third line of the Balmer series for a H atom is: A. 21/100R. B. 100/ 21R. C ... Wavelength of 3rd line of Balmer, λ=21R1 00 ... How satisfied are you with the answer?
Top answer
Balmer series n1 = 2 The third line of Balmer series n2 = 5 Rydberg equation 1λ = Rz2 [ 1n12 - 1n22 ] 1λ = (10967800) (1)2 [ 122 - 152 ] 1λ
