Quantization, Doppler shift and invariance of the speed of light: some didactic problems and opportunities

I discuss some of the didactic problems in the introduction to quantum physics based on the concept of photon. I specifically argue that the derivation of the photon energy from the relativistic Doppler shift offers stimulating didactic opportunities. A detailed form of this derivation reveals the subtle link between relativity and quantization, and also helps in elucidating the meaning of the invariance of the speed of light
