What is Visible Light Spectrum

Visible light spectrum refers to the range of wavelengths of electromagnetic radiation that can be detected and perceived by the human eye. It encompasses the colors that we see in our everyday lives. The visible light spectrum spans from approximately 400 to 700 nanometers (nm) in wavelength.

Visible light is just a small portion of the larger electromagnetic spectrum, which includes various forms of radiation such as radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays. Within the visible light spectrum, different colors are represented by different wavelengths. For example, violet light has the shortest wavelength, around 400 nm, while red light has the longest wavelength, around 700 nm.

Understanding the visible light spectrum allows for the design and production of lighting products that meet specific requirements. Different lighting technologies, such as incandescent bulbs, fluorescent lamps, and LED lights, emit light at different wavelengths within the visible light spectrum. By manipulating the wavelengths of light, lighting designers can achieve desired effects, such as color temperature and color rendering capabilities.
