# Wavelengths of Light: Color Wheel & Measurements

• 6913
In summary, the conversation is about the search for wavelengths of intermediate colors, such as pink, aquamarine, and turquoise. The person is wondering if it is possible to find a color wheel or other resource that provides these wavelengths. However, it is mentioned that only the wavelengths for colors in the spectrum are available and everything else is a mixture of different wavelengths. The other person suggests searching on Google for more information.

Been looking on the internet for a long time, trying to find wavelengths of light. The sites I've seen have the wavelengths of the basic colours (red, blue, green etc.). I'm looking for the wavelengths of intermediate colours, (pink, aquamarine, turquoise etc.). Is it possible to find a colour wheel or something that would give the wavelength? Help much appreciated

sorry, no such wavelength …

the only wavelengths are for the colours in the spectrum …

everything else is a mixture of different wavelengths (a "symphony of colour")

Is it possible to find what the mixture is? Thanks so much for your help

hi 6913!

there's a spectrum of magenta at http://www.academictutorials.com/graphics/graphics-light-and-color.asp" [Broken]

for other colours, try google-searching

Hello, as a scientist, I can understand your frustration in finding the exact wavelengths of intermediate colors. The reason for this is because the visible spectrum of light is continuous, meaning there are an infinite number of colors between the basic colors (red, blue, green, etc.). Therefore, it is not possible to give an exact wavelength for each intermediate color.

However, there are some general guidelines that can help you estimate the wavelengths of these colors. The color wheel, which is a visual representation of the visible spectrum, can be a useful tool in this case. The basic colors (red, blue, green) are located at the primary positions on the color wheel, while the intermediate colors (pink, aquamarine, turquoise) are located in between these primary colors.

Based on this, we can estimate that the wavelength of pink would fall somewhere between the wavelengths of red and blue, while the wavelength of aquamarine would fall between blue and green. Keep in mind that these are just estimates and the exact wavelengths may vary depending on the specific shade of the color.

Another helpful resource could be a light spectrum chart, which displays the wavelengths of different colors in a visual format. This can give you a better idea of the range of wavelengths for each color.

In conclusion, while it may not be possible to find the exact wavelengths of intermediate colors, using a combination of the color wheel and a light spectrum chart can help you estimate the approximate wavelengths. I hope this information helps in your research.

## 1. What is the color wheel and how does it relate to wavelengths of light?

The color wheel is a circular diagram that shows the relationship between different colors. It is based on the scientific understanding that colors are created by different wavelengths of light. The color wheel starts with red and progresses through orange, yellow, green, blue, and purple, with all the shades in between. This progression is based on the wavelength of each color, with red having the longest wavelength and purple having the shortest.

## 2. How are wavelengths of light measured?

Wavelengths of light are measured in nanometers (nm), which is one billionth of a meter. This is because the length of light waves is very small and cannot be measured in larger units. In the visible light spectrum, red has a wavelength of approximately 700 nm, while violet has a wavelength of around 400 nm.

## 3. What is the relationship between wavelength and color?

The relationship between wavelength and color is that the shorter the wavelength, the bluer the color will appear, and the longer the wavelength, the redder the color will appear. This is because blue light has a shorter wavelength than red light. The color wheel is organized in a way that reflects this relationship, with blue shades on one side and red shades on the other.

## 4. How do different wavelengths of light affect our perception of color?

Our perception of color is directly affected by the different wavelengths of light that are reflected or absorbed by an object. For example, a blue object appears blue because it absorbs all wavelengths of light except for blue, which it reflects. This is why a red object appears red, because it absorbs all other wavelengths of light except for red. Our eyes and brain perceive these reflections as different colors.

## 5. Can we see all wavelengths of light?

No, we cannot see all wavelengths of light. The visible light spectrum, which is the range of wavelengths that our eyes can detect, is only a small portion of the entire electromagnetic spectrum. Other wavelengths, such as radio waves, infrared, and ultraviolet, are invisible to the human eye. Animals, such as bees and birds, can see a wider range of wavelengths than humans.
