A successful feature of Bohr model was that his theory accounted for the Rydberg equation, which made it possible to calculate wavelengths of the hydrogen spectral lines. Using the Rydberg equation, calculate the wavelength (in nm) of a spectral line produced in the hydrogen spectrum, when an electron falls from the 4th energy level to the 2nd energy level. Which region of the electromagnetic spectrum does this spectral line belong to? [Note: Rydberg constant, RH=109,678,00m^(-1)

Answer:
it is balmer series ..
because electron is coming from higher energy level to 2nd energy level which is balmer series..
use the formula
refer
nue bar=RH{1/n2-1n1}
put in place of nue bar=1/lamda
u have to find lamda
hope so helpful..
