Fiber optic cables use wavelengths of visible light to transmit data. (Some use infrared as well.) They use red and above with the higher wavelengths being of higher speed and quality. The higher the wavelengths of light used, the more expensive the equipment is.
No, not all electromagnetic radiation in the optical portion of the spectrum is visible to the human eye. The visible portion of the spectrum ranges from about 400 nanometers (violet) to 700 nanometers (red), but there are wavelengths outside of this range that can also be classified as part of the optical spectrum, such as ultraviolet and infrared light.
Yes, the visible portion of the electromagnetic spectrum consists of wavelengths between approximately 400 to 700 nanometers. This range is a small portion of the entire electromagnetic spectrum, which includes radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays.
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
True. The visible portion of the electromagnetic spectrum represents a specific range of wavelengths that can be detected by the human eye, making up a significant portion of the overall electromagnetic spectrum.
False
That's the portion of the spectrum that we call "gamma rays".
Visible light is in the portion of the electromagnetic spectrum between infrared (IR) and ultraviolet (UV) light.
Radio waves are electromagnetic waves occurring on the radio frequency portion of the electromagnetic spectrum.
Radio waves, which are used for communication and broadcasting. Visible light, the portion of the electromagnetic spectrum that is visible to the human eye. X-rays, which are used for medical imaging and security screening.
No, it is only a very small portion.
Gamma rays have the shortest wavelength in the electromagnetic spectrum. They have the highest frequency and carry the most energy of all the electromagnetic waves.
