Which term describes energy carried by waves such as light or radio waves?

• A. Thermonuclear Energy
• B. Open System
• C. Electromagnetic Energy
• D. Conductors

Answer: (C)

The energy carried by waves such as light or radio waves is electromagnetic energy. Electromagnetic waves consist of oscillating electric and magnetic fields that propagate through space, so they don’t need a medium to travel. Light from the sun and radio signals both are forms of this energy, often described as radiant energy.

Thermonuclear energy refers to energy from nuclear fusion, not wave energy. An open system is a thermodynamics term about exchanges with the surroundings, not a type of energy. Conductors describe materials that allow electric charge to move, not the energy carried by waves.
