Abstract

High light refers to intense electromagnetic radiation that occurs in both visible light and ultraviolet (UV) ranges. Visible light is essential for life because it helps plants perform photosynthesis, turning light into chemical energy that feeds the food chain. UV radiation, found just beyond the visible spectrum, has three types: UVA, UVB and UVC. UVB and UVC can cause serious biological damage. Ionizing radiation is more harmful than non-ionizing radiation because it can go through biological tissues and damage DNA, leading to mutations and genetic disorders.
