Which term refers to energy from the sun reaching Earth and primarily having short wavelengths?

• A. Infrared radiation
• B. Ultraviolet radiation
• C. Solar radiation
• D. Microwave radiation

Answer: (C)

Solar radiation is the energy from the sun that reaches Earth. It spans a broad range of wavelengths, including visible light and near-infrared, with some ultraviolet as well, though the atmosphere shapes how much of each portion arrives at the surface. Among the terms listed, solar radiation best fits because it refers to the overall solar energy arriving at Earth, while infrared, ultraviolet, and microwave describe only specific parts of that spectrum. In everyday usage, solar radiation is the umbrella term for the sun’s energy reaching our planet.
