1.	Monochromatic radiation of wavelength `lambda` is incident on a hydrogen sample in ground state. hydrogen atoms absorb a fraction of light and subsequently and radiation of six different wavelength .Find the value of `lambda`A. `203 nm`B. `95 nm`C. `80 nm`D. `73 nm`
Answer» Correct Answer - B In the emittion spectrum `10` lines are observed, so the energy level `n` to which the sample has been excited after absorbing the radiation is given by `(n (n - 1))/(2) = 10` `"which given"` `n = 5` so, `(h c)/(lambda) = 13.6 (1 - (1)/(5^(2))) eV` `(1242)/(lambda) eV- nm = 13.6 xx (24)/(25) eV` `:. lambda = 95 nm`
