# what is the wavelength of white ?

Asked By: luobo1689 | Last Updated: 2022-05-06

what is the wavelength of white？

400 – 700 mmHence, white cannot be assigned to a single wavelength as it is composed of wavelengths of different colors. The white light has a wavelength between the ranges of 400 – 700 mm.

Subsequently,Does white color have a wavelength?

Visible light is electromagnetic radiation with wavelengths ranging from roughly 400 and 700 nanometers. In physics, a color is visible light with a specific wavelength. Black and white are not colors because they do not have specific wavelengths. Instead, white light contains all wavelengths of visible light.

Thereof,What is the wavelength of black?

Since there is no light, there is no wavelength to be measured. 'Black' is just your brain's interpretation to the absence of signals from the receptors in your eyes.

Regarding this,Is white a short wavelength?

The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light. The white light is a mixture of the colors of the visible spectrum.

Besides,What is the spectrum of white?

The spectrum of white light consists of six basic colours arranged in a specific order: red, orange, yellow, green, blue and violet.

### Why is black not a color?

As any rainbow will demonstrate, black isn't on the visible spectrum of color. All other colors are reflections of light, except black. Black is the absence of light. Unlike white and other hues, pure black can exist in nature without any light at all.

### Why pink is not a color?

If colours were simply a naming scheme for wavelengths then pink is not one, because it is made up of more than one wavelength (it's actually a mix of red and purple light). If you took a laser and tuned it across the visible wavelengths, from infrared through to ultraviolet, you would not pass pink on the way.

### What colours make white light?

White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow. Combining primary colors of light like red, blue, and green creates secondary colors: yellow, cyan, and magenta. All other colors can be broken down into different combinations of the three primary colors.

### Can we see white light?

The Visible Spectrum Visible light is the light that we can see, and thus is the only light detectable by the human eye. White light is visible light, and it contains all the colors of the rainbow, from red to violet. The range of visible wavelengths is 400 to 700 nanometers.

### What is the longest wavelength?

Radio wavesRadio waves have the longest wavelength, and gamma rays have the shortest wavelength.

### Is sunlight a white light?

The fact that you see all the fundamental colors present in a rainbow (which is sunlight split by mist) and no colors are missing is direct evidence that sunlight is white. The sun emits all colors of visible light, and in fact emits all frequencies of electromagnetic waves except gamma rays.

### Is GREY a color?

Grey or gray (American English alternative; see spelling differences) is an intermediate color between black and white. It is a neutral or achromatic color, meaning literally that it is "without color", because it can be composed of black and white.

### Is clear a color?

Is clear a color? We think so. You may not, and that's fine. Looking ahead to 2020, Xerox today announced its inaugural Color of the Year: Clear.
