SUMMARY
The discussion centers on the concept of frequency in quantum mechanics as presented in Bransden's "Quantum Mechanics" 2nd edition, specifically on page 61. It establishes that the absolute value of frequency, denoted as E = hv (where v represents frequency), lacks physical significance in non-relativistic quantum mechanics and quantum field theory in flat spacetime. The key takeaway is that only differences in energy hold physical relevance, not absolute values.
