Which energy type is commonly associated with light and electromagnetic radiation?

• A. Heat
• B. Radiant
• C. Nuclear
• D. Mechanical

Answer: (B)

Radiant energy is the energy carried by electromagnetic radiation, including visible light. Light is itself a form of electromagnetic radiation, so it’s described as radiant energy. This distinguishes it from other energy types: heat relates to temperature and thermal energy transfer, nuclear energy comes from processes in atomic nuclei, and mechanical energy concerns the motion or position of macroscopic objects. Radiant energy directly describes the energy transported by light and other EM waves.
