Question

( frac{1}{lambda}=R cdotleft(frac{1}{left(n_{i}right)^{2}}-frac{1}{left(n_{f}right)^{2}}right) )
( R cdotleft(frac{1}{infty}-frac{1}{(1,2)}right) )
( lambda rightarrow frac{1}{R}=frac{1}{1097 times 10^{-7}} )
( =9.1 times 10^{-8} mathrm{m} )
( lambda=91 n mathrm{m} )

# The wavelength of radiation emitted, when in Het electron falls from infinity to stationary state would be (R = 1.097 x 107 m-1)

Solution
