What describes energy emitted by one body traveling through a medium or through space to be absorbed by another body?

• A. Infrared
• B. Radiation
• C. Ultraviolet
• D. Radiofrequency Radiation

Answer: (B)

Radiation is the transfer of energy from a source as electromagnetic waves (or particles) that move through space or a medium and can be absorbed by another body. This mechanism allows energy to travel without direct contact or a surrounding medium, such as sunlight reaching Earth through the vacuum of space. The other options are specific types of radiation defined by wavelength: infrared, ultraviolet, and radiofrequency radiation are particular parts of the electromagnetic spectrum, not the general process itself.
