Energy carried by light waves or photons is called?

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

Answer: (B)

Light energy is the energy carried by light waves as they travel and interact with matter. Light waves are electromagnetic waves, so they transport energy through space; photons—the particle form of light—carry discrete amounts of energy determined by their frequency (E = hf, or E = hc/λ). This radiant energy can heat surfaces, drive chemical reactions, or power processes like photosynthesis. It’s distinct from mechanical energy (energy of moving or resting objects), thermal energy (related to temperature and microscopic motion), and electrical energy (energy of electric charges).
