The simplest answer, without getting bogged down in details that don’t change the answer, is found in the classic equation: E^2=m^2c^4+p^2c^2. We know that E=hf

The simplest answer, without getting bogged down in details that don’t change the answer, is found in the classic equation: E^2=m^2c^4+p^2c^2. We know that E=hf=pc, so we also know that the answer to your question is “Yes” and “No” respectively.
