In frequency modulation the maximum frequency deviation is directly proportional to the product of modulation index (beta) and modulating frequency where beta is given by(Kp*Am)/fm. Now frequency deviation becomes (Kf *Am). So the frequency deviation depends on the magnitude of the modulating message signal.but not ntgr modulating signal frequency fm.Hence the deviation ratio is in the ratio 1:1

1:1 because according to relation frequency deviation=K.Vm.fc in this relationship fc is same and K (bolzth man constant) constant so frq deviation depends only on amplitude of the msg signals hence no deviation due to carrier frq
