In a vacuum photons of lower energy

Webwith photons so there is no requirement for an intervening medium radiating thermal energy can be transferred in the vacuumed medium the biggest example of radiation heat transfer mechanism is heat that is coming from the son to earth heat transfer definition facts britannica - Aug 07 2024 WebShorter wavelengths have higher energy as they oscillate faster, while larger wavelengths, which oscillate more slowly, have lower energy. To obtain the photon energy, you need to multiply the velocity of the light ‘ c ’ in the vacuum by the Planck constant ‘ h ’ and divide this by the wavelength of the photon ‘ λ ’.
