Monochromatic radiation of wavelength 'x' is incident on a hydrogen sample in ground state . Hydrogen atoms absorb a fraction of light and subsequently emit radiation of six wavelengths. Find the value of 'x'????
Dear student from the eqn. for ground staten(n-1)/2 = 6n^2 – n – 12 = 0n^2 – 4n + 3n – 12 = 0(n-4) (n+3) = 0n = 4Therfore,1/x = R*1^2(1/1^2 – 1/4^2)1/x = R*(1 – 1/16) => 15R/16x = 16/15R = 16*10^7/(15 *1.09) is the answer. = 0.978593 * 10^7 meter. RegardsArun (askIITians forum expert)
