Answer» 325 nm 743 nm 518 nm 1035 nm Solution :As energies are additive, `E = E_(1) + E_(2)` or `(HC)/(LAMDA) = (hc)/(lamda_(1)) + (hc)/(lamda_(2)) or (1)/(lamda) = (1)/(lamda_(1)) + (1)/(lamda_(2))` But `lamda = 355 nm, lamda_(1) = 680NM,` `:. (1)/(355) = (1)/(680) + (1)/(lamda_(2))` or `(1)/(lamda_(2)) = (1)/(355) - (1)/(680) = (325)/(355 xx 680)` or `lamda_(2) = (355 xx 680)/(325) = 745nm`
