Gravitational influences on relativistic mass-energy and quantum energy-frequency:

Gravity interacts with both mass (whether in the form of matter or energy) and electromagnetic waves, regardless of their energy or frequency. A change in gravitational potential directly influences the effective mass-energy or the energy-frequency relationship of these entities.

For electromagnetic waves, the energy is entirely kinetic, described by the relationship f = E/h, where h is Planck's constant, and f is the frequency. The frequency reflects the wave's kinetic energy and dynamically shifts under varying gravitational potentials, showcasing its interaction with gravity.

By the equivalence principle, energy—whether kinetic or relativistic—corresponds to an effective mass, expressed as m = E/c^2. This principle highlights the interplay between gravitational fields, electromagnetic energy, and effective mass, providing deeper insights into their mutual influence across different physical scenarios.
