Thanks, Peter. I appreciate these clarifications. It is points like this that helps a person who knows very little about physics follow the extraordinary discoveries and theories of quantum mechanics and cosmology we are inheritors of today, and to be present day observers of discoveries like...
Thanks for this. Your answer is extremely helpful. I can see that I was actually asking two different questions. Regarding photons, I have never been clear on references to "high energy photons". Would that be a direct reference to frequency, e.g., gamma rays?
And subsumed within my question, I...
I often read of photons manifesting different levels of energy. I know that energy increases as wavelength decreases and frequency increases. Are there other ways particles gain or lose energy? As water boils heat energy is transferred to the water causing water molecules to move faster and to...
