The largest wavelength in the ultraviolet region of the hydrogen spectrum is 122 nm. The smallest wavelength in the infrared region of the hydrogen spectrum (to the nearest integer is) |

Answer» 802 nm i.e. `1/(122)=R (1/1^(2)-1/2^(2))..........(i)` SMALLEST wavelength in UR region is given by transition `noo" to "n=3` `1/lambda =R (1/3^(2)-1oo) ............(ii)` Solving equation (i) and (ii), `lambda=823.5nm` |
