Mass, Momentum, Force and Energy of Photon and Subatomic Particles, and Mechanism of Constant Light Speed Based on Yangton & Yington Theory

摘要

The meanings of Mass, Momentum, Force and Energy of a substance are clearly defined. Their relationships to each others are discussed. The reasons that a Photon has energy E = h/λ and momentum P = h/λ are explained. Light travels in vacuum at a constant speed C = 3 × 10~8 m/sec while converting from Wu's Particle through the separation and ejection processes from its parent substance is discussed in details based on Yangton and Yington theory. In Black Body radiation, a Photon emitted at high temperature having smaller size, higher frequency and higher energy is also explained.
