Black is not actually a colour associated with a unique wavelength of light. Black objects absorb nearly all the light at wavelengths our eyes can detect. When we look at something black we are actually seeing 'no light' (or very little compared to the surroundings).
White light is the exact opposite; white objects hardly absorb any light. When we look at white objects, our eyes take in light at all wavelengths and we interpret this as the 'colour' white.
Visible light wavelength range: 390 to 750 nm (there are 1,000,000 nm in 1 mm)
Any light outside this range cannot be seen by humans and could be called 'black'

What color of light has the longest wavelength and the shortest?
The color RED has the longest wavelenth, and the color VIOLET has the shortest wavelenth. ---- Also Wavelenth is inversely propotional to frequency, so we can also say that color VIOLET has longest frequency and color RED has the shortest. VIBGYOR V-Violet (Highest Frequency, Shortest Wavelenth) I-Indigo B-Blue G-Green Y-Yellow O-Orange R-Red (Highest Wavelenth,Shortest Frequency)
Is black the absence of color?
Is black the absence of color? Well, the answer is all in perspective. In light Black is the absence of color and white is the essence of color, but in paint black is the essence of all color and white is the absence of color.
Is black an actual color?
No. Technically black is not considered a color.
What is the distance between on point of a wave to the same point in the next wave?
wavelenth
Is white every color or is black?
White is every color, whereas black is the absence of color.

Principle of infrared spectroscopy?
wavelenth mesured wavenoumber
Why the use of K2Cr2O7in uv callibration?
it has specific wavelenth
What are the Advantages of WDM?
disadvantages of wavelenth division multiplexing
What color is a black bird?
A black bird is black in color.
Why is black not a color and white is a color?
Black is the absence of all color. White is the presence of all color. Therefore, black has no actual color.
Is black really black?
If you are referring to skin color, no. If you mean the color black but not a skin color, then yes.

purple
What is black the color?
Black does not reflect. It absorbs all colors of light.
What color are the belts for the Cubs?
Black Color
Which wavelenth of electromagnetic radiation carries the most energy?
Gamma rays.
What is the equation for calculating wave speed?
wave speed= frequency/wavelenth
