Question

Calculate the wavelength of radiations emitted producing a line in Lyman series,when an electron falls from fourth stationary state in hydrogen atom (RH=1.1×107m−1)

Answer 1

Hope this helps u
U cn use the formula of hydrogen spectrum in this to solve it

Answer 2

Answer:

λ=0.9696×10−7m)

Explanation:

1λ=RH[1n21−1n22]

Given  RH = 1.1×107 for Lyman series n1=1and n2=4 (gives )

Therefore ,

1λ=1.1×107[112−142]

λ=0.9696×10−7m
