Ultraviolet, visible, and near-infrared light

Ultraviolet, visible, and near-infrared light are parts of the electromagnetic spectrum, each with different wavelengths. Ultraviolet (UV) light has shorter wavelengths than visible light, enabling it to cause chemical reactions like sunburns. Visible light is the range our eyes can see, spanning from violet to red; it's what allows us to perceive colors. Near-infrared (NIR) has longer wavelengths than visible light and is often used in thermal imaging and remote sensing, as it can penetrate materials like skin and some fabrics. These distinctions are essential for applications in medicine, communications, and technology.
