What is the wavelength of visible light?
approximately 0.4 to 0.7 µm
The visible wavelengths cover a range from approximately 0.4 to 0.7 µm. The longest visible wavelength is red and the shortest is violet. Common wavelengths of what we perceive as particular colours from the visible portion of the spectrum are listed below.
What are the different wavelengths of the visible spectrum?
The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10-7 m, which is red).
What is the color spectrum of visible light?
The spectrum of wavelengths we can see (visible light) ranges from 380 nm (blue) to 700 nm (red). Below this spectrum is ultraviolet, after which we have blue and at the top of the spectrum of visible light is red, after which we have infrared.
What is the wavelength and frequency of visible light?
Visible light falls in the range of the EM spectrum between infrared (IR) and ultraviolet (UV). It has frequencies of about 4 × 1014 to 8 × 1014 cycles per second, or hertz (Hz) and wavelengths of about 740 nanometers (nm) or 2.9 × 10−5 inches, to 380 nm (1.5 × 10−5 inches).
What is the wavelength of each color?
A spectrally pure or monochromatic color can be produced by a single wavelength. For example, an orange color is associated with a wavelength of 600 nm….Nature of Color.
| Spectral region | Range of wavelength in nm | Subregion |
|---|---|---|
| Visible | 380-430 430-500 500-520 520-565 565-580 580-625 625-740 | Violet Blue Cyan Green Yellow Orange Red |
What color has the highest wavelength?
red light
On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow.
What is the shortest wavelength of visible light?
violet light
Visible light may be a tiny part of the electromagnetic spectrum, but there are still many variations of wavelengths. We see these variations as colors. On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength.
