Experiments questioning the E=hw relationship for low-energy photons suggest it may need correction, as E=hw is not a fundamental law like thermodynamic or Newtonian laws. Instead, it represents a correlation between a massless particle's energy and its wave's angular frequency. Some discussions hint at research on time-dependencies of Planck's constant (h), but substantial findings remain elusive. The conversation emphasizes the need for further investigation into the nuances of photon energy. Overall, the validity of E=hw in specific contexts continues to be a topic of scientific inquiry.
