Determine the minimum wavelength that hydrogen in its ground state can

1.	Determine the minimum wavelength that hydrogen in its ground state can obsorb. What would be the next smaller wavelength that would work?A. `133 nm`B. `13.3 nm`C. `10.3 nm`D. `103 nm`
Answer» Correct Answer - D When wavelength is maximum, the energy is maximum. Hence, this is from the ground state to the first excited state, for which the energy is `13.6 eV - 3.4 eV = 10.2 eV` hence, the required wavelength is `122 nm` The next possibility is to jump from the ground state to the second excited state which requires `=m 13.6 xx 1.5 = 12.1 eV`. Hence, it correcponding to a wavelength `lambda = ( c)/(v) = (hc)/(E_(3) - E_(1)) = ((6.63 xx 10^(-34)) xx(3 xx 10^(8)))/((12.1) xx (1.6 xx 10^(-19))) = 103 nm`
