Energy in the form of moving waves of light.

• A. Thermal energy
• B. Electrical energy
• C. Mechanical energy
• D. Light energy

Answer: (D)

Light energy is the energy carried by moving waves of light. Light is electromagnetic radiation that travels as waves (or as particles called photons) and transfers energy as it moves. This is different from thermal energy, which comes from the random motion of particles and relates to temperature; electrical energy comes from moving charges or electrical circuits; and mechanical energy is the energy of motion or position of an object. So the energy described by moving waves of light is light energy, the energy carried by those light waves.
