Hello everybody, In one of my assignments I have lost a substanial portion of the grade for one problem because I haven't assumed that the energy of a Gamma ray = hf, I thought this was wrong, and that nothing in the statement says that it consists of only one photon. In fact, it says "high energy ray." Does it make sense to you ? Should I make that assumption in the future? Should I talk to the prof about it?! Thanks!
