Jun 7, 2024 · The wavelengths of visible light are: Violet: 380–450 nm (688–789 THz frequency) Blue: 450–495 nm; Green: 495–570 nm; Yellow: 570–590 nm; Orange: 590–620 nm; Red: 620–750 nm (400–484 THz frequency) Violet light has the shortest wavelength, which means it has the highest frequency and energy. Red has the longest wavelength, the ...

- What Is The Visible Light Spectrum
The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see. In fact, most of the light in the universe is invisible to our eyes. The light we can see, made up of the individual colors of the rainbow, represents only a very small portion of the electromagnetic spectrum. Other types of light include rad...
Light travels in waves, much like the waves you find in the ocean. As a wave, light has several basic properties that describe it. One is frequency, which counts the number of waves that pass by a given point in one second. Another is wavelength, the distance from the peak of one wave to the peak of the next. These properties are closely and invers...
To study the universe, astronomers employ the entire electromagnetic spectrum. Different types of light tell us different things. Radio waves and microwaves, which have the lowest energies, allow scientists to pierce dense, interstellar clouds to see the motion of cold gas. Infrared light is used to see through cold dust; study warm gas and dust, a...
White light is dispersed by a glass prism into the colors of the visible spectrum. The visible spectrum is the band 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).
Blue and purple light have short waves, around 400 nm. Shorter waves vibrate at higher frequencies and have higher energies. Red light has a frequency around 430 terahertz, while blue's frequency is closer to 750 terahertz.
Apr 10, 2022 · A low-energy radio wave has a low frequency as a wave, while a high-energy X-ray at your dentist’s office is a high-frequency wave. Among the colors of visible light, violet-light photons have the highest energy and red-light photons have the lowest.

What is the difference between blue and purple light?
The excited electrons in a gas emit a discrete spectrum. The wavelength of a light wave is inversely proportional to its frequency. Light is often described by it's wavelength in a vacuum. Light ranges in wavelength from 400 nm on the violet end to 700 nm on the red end of the visible spectrum.
