Sunlight, also known as daylight or visible light, refers to the portion of electromagnetic radiation emitted by the Sun that is detectable by the human eye. It is one form of the broad range of electromagnetic radiation produced by the Sun. Our eyes are particularly sensitive to this specific range of wavelengths, enabling us to perceive the Sun and the world around us.
- Sunlight is only one form of electromagnetic radiation emitted by the Sun.
- Sunlight is only a very small part of the electromagnetic spectrum.
- Sunlight is the form of electromagnetic radiation that our eyes are sensitive to.
