The Triangle of Light Waves

Visible, Ultraviolet, and Infrared

The triangle of Visible, Ultraviolet, and Infrared represents key regions of the electromagnetic spectrum, each characterized by its wavelength and impact on the natural world. Together, these types of light shape our perception and interaction with the environment.

1. Visible: The visible spectrum includes wavelengths perceivable by the human eye, ranging from 400 to 700 nanometers. It allows us to see colors from violet to red, forming the basis of how we visually interpret the world.

2. Ultraviolet (UV): Ultraviolet light has shorter wavelengths than visible light, lying beyond the violet end of the spectrum. While invisible to the naked eye, UV light has important effects, such as producing vitamin D in the skin and sterilizing surfaces, but it can also cause sunburn and damage to DNA.

3. Infrared (IR): Infrared light has longer wavelengths than visible light, found beyond the red end of the spectrum. It is primarily associated with heat radiation, enabling technologies like thermal imaging and remote controls.

   
   

Balancing visible, ultraviolet, and infrared light reveals the interconnected nature of light’s role in life and technology.
