When in hydrogen like ion, electron jumps fromn = 3 to n = 1, the emitted photon has frequency 2.7 xx 10^(15) Hz. When electron jumps from n=4 to n=1, the frequency is |

Answer» `1.6xx10^15` Hz `UPSILON = RC[1/1^2-1/3^2]` or `2.7xx10^15=Rcxx8/9` ….(i) When the electron jumps from n=4 to n=1 `upsilon.=Rc[1/1^2-1/4^2]=Rcxx15/16` …(ii) From eqn (i) and (ii) `(upsilon.)/(2.7xx10^15)=15/16xx9/8` `upsilon.=15/16xx9/8xx2.7xx10^15=2.8xx10^15` Hz |
