Photons have zero mass, which allows them to travel at the fastest possible speed in the universe, the speed of light. However, they do have energy and momentum.
Do photons ever run out of energy
Did you know?
WebHowever, matter creation is allowed by these laws when in the presence of another particle (another boson, or even a fermion) which can share the primary photon's momentum. Thus, matter can be created out of two photons. The law of conservation of energy sets a minimum photon energy required for the creation of a pair of fermions: this ... WebT h e far-red region of X > 0.7 p. (photon energy 1.77 e V ) b y itself is inactive. Although absorbed, the energy of these photons does not accom- plish photosynthesis. B u t as a supplement to photons with energies > 1.82 e V (X 0.68 [/.) the far-red radiation becomes fully effective. T w o quantitative conversions are postulated (Calvin, 1962).
