Answer» Solution :CALCULATION of transitionenergyof Bohr.s1 to5 orbit. `10^(7)"earg" =1j` `2,18 xx 10^(11) "earg"= (?)` `(2.18xx 10^(11) "earg" xx 11)/( 10^(7)"earg" )= 2.18 xx 10^(18)` Groundstateenergyof hydrogen`E_(1)=2 .18 xx 10^(18) J` bohrorbitof hydrogen is one son=1and `E_(1)` electronrequiredfor transitionof electronin`n_(1)` to`n_(5)` is `Delta E` Calculationof emittedwavelengthwhenelectronreturnto GROUNDSTATE : `lambda= (hc )/( Delta E)` |
