Final answer:
The transferred energy via space by electromagnetic waves is electromagnetic radiation, which moves at the speed of light in a vacuum and shows wave-particle duality.
Step-by-step explanation:
The energy that is transferred through space by electromagnetic waves is called electromagnetic radiation. This includes various forms such as gamma rays, x-rays, ultraviolet light, infrared light, microwaves, and radio waves. Electromagnetic waves travel through a vacuum at the speed of light, which is approximately 3.00 × 10⁸ m/s, and exhibit both wavelike and particle-like properties, a concept known as wave-particle duality. Electromagnetic radiation can be produced by exciting matter to higher energies, for example, by heating.
The correct answer to the question is (c) electromagnetic radiation.
