How is "radiant energy" defined?

Heating a building by radiation from panels containing hot water
Energy that is transmitted in the form of radiation
An automatic instinctive unlearned reaction to a stimulus

The correct answer is: Energy that is transmitted in the form of radiation

Radiant energy is defined as energy that is transmitted in the form of radiation, which encompasses a range of electromagnetic waves. This includes visible light, infrared radiation, ultraviolet light, and other forms of energy that travel through space. Radiant energy is fundamental in various processes, such as photosynthesis in plants, where sunlight (a form of radiant energy) is converted into chemical energy. The other options describe different concepts. Heating a building using radiation from panels refers to the transfer of thermal energy, while instinctive reactions pertain to biological responses to stimuli, and recycling focuses on the reuse of materials. These concepts do not encapsulate the definition of radiant energy, which specifically relates to energy transfer through radiation.
