The ground state energy of hydrogen atom is -13.6eV .If the electrons jump to the ground states from the second excited states calculate the wavelength of the spectral line emitted.( R= 1.1 ×10^7 /m)

use formula for energy of hydrogen like atoms
for states second(n=3) and substract ground state energy.
Convert that energy difference into Joules and use Energy difference = h.(c/wavelength)
where h is planks constant and c is speed of light in vaccum.
