What term describes energy transmitted by waves through space or through a medium?

• A. Radiation
• B. Energy
• C. Ionization
• D. Sound

Answer: (A)

Radiation describes the energy carried by waves as they move through space or through a material. This includes energy from electromagnetic waves like X-rays used in imaging, which can travel across space, and energy moving through a medium. The other terms don’t fit as well: energy is too general a label for motion of energy, ionization is the process of removing electrons, and sound is a specific mechanical wave that requires a medium and doesn’t represent energy transfer through space in general.
