The energy of electron in the nth orbit of hydrogen atom is expressed as `E_(n) = (-13.6)/(n^(2))eV`. The shortest and longest wavelength of Lyman series will be

Options

A. 910 Å
B. 5436Å
C. 1315Å
D. none of these

Answer

A

Explanation

`(1) /( lamda_(min)) = R =[ (1)/((1)^2)- (1)/(oo) ]implies lamda_(min) =(1)/(R ) ~~ 910 Å`
