Question

________ is the transfer of energy through electromagnetic waves, such as light or heat, that can travel through a vacuum.

Explanation:

The question is about a concept in physics (a subfield of Natural Science) related to energy transfer via electromagnetic waves that can move through a vacuum. The term for this is "Radiation" (specifically electromagnetic radiation), as conduction requires a medium and convection also involves a medium (like fluid or gas), while radiation uses electromagnetic waves and can travel in a vacuum (e.g., sunlight reaching Earth through space).

Answer:

Radiation
