Ultraviolet - GCSE Physics Definition
Reviewed by: Caroline Carroll
Published
Ultraviolet, often abbreviated as UV, is a type of electromagnetic radiation that comes from the Sun and is invisible to the human eye. It's part of the electromagnetic spectrum, which also includes visible light, infrared, and other types of radiation. UV light has shorter wavelengths than visible light, which makes it more energetic. While some UV exposure is beneficial, as it helps our bodies produce vitamin D, too much UV can harm the skin and eyes, leading to sunburn or even increasing the risk of skin cancer. Scientists use special instruments to detect and study ultraviolet light because of its important role in the environment and health.
