Monochromatic radiation is incident on hydrogen (H) sample which is in ground state. If the hydrogen atoms emit radiation of ten different wavelengths after absorbing the incident radiation, then the wavlength of the incident radiation is (Let hc=1242eV-nm) |

Answer» 84.4 NM Since , monochromatic radiation is incident on hydrogen SAMPLE which is in ground state. Hence , the energy of ground state is given by ` |E| = 136 eV ` ` (hc)/(lambda) = 136 "" (becauseE = (hc)/(lambda)) ` ` lambda = (hc)/(136) = (1242)/(136) nm ` = 91.3 nm= 95.1 nm Hence , the wavelength of incient radiation is 95.1 nm . |
