21. As the amount of released radiant energy is fairly high, significant heating of the illuminated object can occur. 22. In the spring, the sun's radiant energy warms the ground and evaporates the moisture in it, he noted. 23. They can perish together, converting their combined rest energy into photons having electromagnetic radiant energy , but no rest mass. 24. If the temperature is only 75, but the radiant energy and humidity are high, a player could suffer heatstroke. 25. The emissivity of sea water has been modeled as a function of its temperature, salinity, and radiant energy frequency. 26. Heating by radiant energy is observed every day, the warmth of the sunshine being the most commonly observed example. 27. In fact, the energy of the waves is not related directly to their frequency, but rather to their radiant energy . 28. Also the reason why I suspect radiant energy to be a sock of banned user wikisunn I point out here: 29. The experiment then detected their oscillation rate from one state to another as the changes yielded tiny flashes of radiant energy . 30. An approximation of this radiant energy is described by the formula of the quadrupolar radiation of Albert Einstein ( 1918 ).
