AM Physics Test 1 Leave a Comment / By fawadtwopointo@gmail.com / August 22, 2025 Welcome to your AM Physics Test 1 In nonrelativistic quantum theory, a complete set of commuting observables is primarily used to: Define a unique potential Eliminate measurement back-action Label mutually exclusive measurement outcomes Remove degeneracy from all spectra None Which interpretation treats the wavefunction as a tool for computing probabilities without asserting underlying reality? de Broglie–Bohm Many-worlds Copenhagen Objective collapse None In scattering theory, the physical meaning of the S-matrix unitarity condition is that: Interaction range is finite Energy is exactly conserved for bound states only Total probability is conserved in all scattering processes Cross sections are independent of energy None In relativistic quantum field theory, microcausality requires that: Measurements at spacelike separation cannot influence each other Vacuum fluctuations are absent All fields are gauge fields Interactions vanish beyond a fixed length scale None Renormalization group “flow” primarily describes how: Boundary conditions change under time evolution Observables transform under spatial rotations Effective couplings change with the scale of observation Gauge choices alter particle content None None Time's up
