It is not invalid; indeed since f = c / λ one has for the energy of a photon E = h c / λ by direct substitution. But your teacher might have wanted to be cautious because there is another equation like it, the de Broglie formula for momentum and wavelength, p = h / λ. If you combine these very naively you get E = p c, a totally non ... bread and better columbus
