Energy of each photon absorbed
`E=hv=(hv)/lambda`
`E=(6.63xx10^(-34)Js xx 3 xx 10^8 m//s)/(4530xx10^(-10)m)`
`=4.39xx10^(-19)` J
Energy of each photon emitted E=hv=`(hv)/lambda`
`=(6.63xx10^(-34)Js xx 3 xx 10^8 m//s)/(5080xx10^(-10)m)`
`=3.92xx10^(-19)` J
Energy fraction emitted
`=(0.53(3.92xx10^(-19)))/(4.39xx10^(-19))xx100=47%`
