If your sky is blue because blue has shorter wavelengths than purple why isn't the sky purple?

We decided to call light by different names depending on what range its wavelengths fell into, and the names we chose (in English) were "red" for some of the longest ones we could see, "green" for some a bit shorter, and "blue" for some even shorter than that. I really get the feeling you were trying to ask a different question (with a better answer than "because they are") here, but I'm not sure what it might be.

What color has a wavelength shorter than blue?
The colors with a wavelength shorter than blue are the violet or purple colors. They have shorter wavelengths because they are higher on the electromagnetic spectrum, meaning they have higher frequency. They also have higher energy, too.
What wave length of light is the shortest?
Violet is actually the shortest wavelength, as you consider the color spectrum. After blue comes indigo, then violet. So blue is the third shortest. The color spectrum ranges from red to violet, with red being the longest. Naturally, violet would then be the shortest. Of course this goes for human visible wavelengths. Ultraviolet light is shorter in wavelength, but not human visible. Xrays have even shorter wavelengths, but they also are not human visible. Gamma rays are the shortest of all, but again not human visible.
How does changing wavelength in the activity vary the light that you see?
The human eye is sensitive to a range of wavelengths within the electromagnetic spectrum, and different wavelengths correspond to different colors. The visible spectrum spans from shorter wavelengths (associated with violet and blue colors) to longer wavelengths (associated with red and beyond). Here's how changing the wavelength can affect the light you see: Color Perception: Shorter Wavelengths (Blue/Violet): Shorter wavelengths are associated with blue and violet colors. As the wavelength decreases, the light appears more towards the blue end of the spectrum. Medium Wavelengths (Green/Yellow): Medium wavelengths are associated with green and yellow colors. Longer Wavelengths (Orange/Red): Longer wavelengths are associated with orange and red colors. As the wavelength increases, the light appears more towards the red end of the spectrum. Intensity and Brightness: Generally, the perception of brightness is more strongly influenced by intensity rather than wavelength. However, changes in wavelength can affect the overall color appearance, and our eyes may perceive certain colors as more or less intense. Color Mixing: Combining light of different wavelengths can result in color mixing. For example, combining red and blue light can produce magenta, while combining red and green light can produce yellow. Interference and Diffraction: Changes in wavelength can also be associated with optical phenomena such as interference and diffraction. These effects can result in patterns of colored fringes or bands, particularly when light interacts with fine structures or passes through narrow openings. Scattering: Shorter wavelengths of light (blue and violet) tend to scatter more than longer wavelengths (red and orange). This is why the sky appears blue during the day; the shorter blue wavelengths are scattered in all directions by the gases and particles in the Earth's atmosphere. Absorption:
Are green wavelengths longer than orange wavelengths?
Sound waves are much longer then light waves.
Which colours are the best emitters?
Colors with shorter wavelengths, such as violet and blue, are generally better emitters of light. This is due to the relationship between color and energy in the electromagnetic spectrum. Shorter wavelengths correspond to higher energy photons. Therefore, materials that emit violet or blue light often have higher energy levels, making them effective emitters. Keep in mind that specific materials and conditions can influence emission properties, so this is a generalization.
What color has a wavelength shorter than blue?
The colors with a wavelength shorter than blue are the violet or purple colors. They have shorter wavelengths because they are higher on the electromagnetic spectrum, meaning they have higher frequency. They also have higher energy, too.
Why are sunsets red purple blue color's wavelengths?
because of how the sun looks through the atmosphere when your looking at it straight on
Red light and blue light are different colors because the light that makes them up has different?
Red and Blue light look different because they have different wavelengths. Red has the longest Wavelength and Blue has a shorter wavelength than Red. Hope this helps :)
Why is the sky light blue in the spring?
The sky is light blue because of the concept of Rayleigh scattering. As the rays of light move, longer wavelengths pass through the air. The shorter wavelengths become absorbed by the gas molecules, thus causing the blue color of the sky.
Are the wavelengths of light at the red end of the spectrum longer or shorter than those at the blue end?
Longer.
Which is hot a blue star or a red star and why?
All stars are hot. Blue stars are the hottest. The hotter a star is, the shorter the wavelength of light it emits. Blue light has a shorter wavelengths than most other colors.
Why is the sky not purple?
earth's atmosphere lets through nearly all waves of light BUT blue wavelengths.
Why Veins carry purplish blood but you do not bleed a bluish-purple blood when the vein is cut?
Veins appear blue because light, penetrating the skin, is absorbed and reflected back to the eye. Since only the higher energy wavelengths can do this (lower energy wavelengths just don't have the *oomph*), only higher energy wavelengths are seen. And higher energy wavelengths are what we call "blue." Blood is never purple although deoxygenated blood is a deeper shade of red than fully oxygenate blood.
Why does an apple look red to the human eye?
The color red, whether in an apple or anywhere else, corresponds to a certain range of wavelengths of light, which are the longer wavelengths of the visible spectrum. Blue is composed of the shorter wavelengths.
How do wavelengths of visible lights relate to energy?
The shorter the wavelength (blue rather than red), the higher the energy.
Is the sky blue because of oxygen?
They blue color of sky is due to the fact that when light waves travel the shorter wavelengths like blue are absorbed and other ones passed with little or no absorption. The blue light is than radiated. Thats why sky looks blue.
Why is purple a color?
Purple is a color because it is a unique combination of blue and red wavelengths on the visible spectrum of light. Our eyes perceive this mix as a distinct color, which we identify as purple.
