Is the part of the electromagnetic spectrum that is visible to the human eye.
The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. It ranges in wavelength from approximately 400 nm (4 x 10 -7 m) to 700 nm (7 x 10 -7 m). It is also known as the optical spectrum of light. What Is Spectrum. Radio waves are a form of electromagnetic radiation which, like visible light or infrared, make up a portion of the entire spectrum. They cannot be perceived by human eyes or ears, and they are not harmful in the environment. The visible light spectrum is a range of light that is visible to the human eye, and is responsible for the colors we see. The spectrum is made up of light waves ranging from approximately 700 nanometers to 400 nanometers. Outside of this visible light spectrum, at the lower end of the frequencies, is infrared light. Visible light is a form of electromagnetic (EM) radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. Generally, visible light is defined as the wavelengths that are visible to most human eyes. EM radiation is transmitted in waves or particles at different wavelengths and frequencies. This broad range of wavelengths is known as the electromagnetic spectrum. Electromagnetic Spectrum. The visible spectrum (or sometimes called the optical spectrum) is the part of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will react to wavelengths in air from about 380 to 750 nm. White light is dispersed by a prism into the colors of the visible spectrum. The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.
