Thank you vela. I shall take your word for it.

First I have to admit that I am not very familiar with the Compton scattering. I just wonder if I assume that in an "absorption of a photon like" interaction of the photon and electron, the whole photon momentum is passed to the electron and as a result the electron gets the relativistic...

In this case the photons do transfer all their energy, the electrons have a range of energies because it is the difference between the photon energy and the ionization energy of the electrons, which varies. increasing intensity increases the current Thanks jtbell, this clarifies very much

Hi guys Thank you for your reply. ZapperZ, I understand that these are very different phenomena. Can you elaborate on what you mean by interaction of the whole solid - in terms of the atomic structure/latice structure? But are they mutually exclusive? If,say, I shine a beam of X-ray onto a...

I understand that in photoelectric effect, the energy of the whole photon is absorbed, freeing an electron. I don't understand why in the case of Compton scattering, the higher energy photon lost part of its energy instead of transferring the whole of its energy to the electron as in...

cepheid, Thanks for your clarification.

So the question in the book is inaccurate? We should always say gravitational potential energy "with respect to a reference point"?
