ultraviolet.
Comment: I agree, or it could simply be blue in some cases.

Is the color of star an effect of its temperature?
Yes. The apparent colour of a star is related to the peak wavelength of the light it emits. According to Wien's displacement law (look it up in Wikipedia) the peak wavelength is inversely proportional to the temperature. The higher the temperature, the shorter the peak wavelength. Wavelength decreases as one moves from red to blue in the visible spectrum, so a red star is cooler than a blue one.
What does a blue and red shift of absorption lines in a spectrum indicate?
Blue shift is a decrease of a signal's wavelength, and/or an increase in its frequency, due to the Doppler Effect. This indicates that the object is moving towards the observer.Red shift is the increase of a signal's wavelength, and/or a decrease in its frequency, due to the Doppler Effect. This indicates that the object is moving away from the observer.
Why does blue light scatter more than red light?
blue light has shorter wavelength than the red light.scattering of light is more when wavelength is small.
What is the fifth color in the color spectrum?
blue
Why does the sky appear blue in the day time?
The color blue is the result of a particular wavelength of light (it is in the shorter wavelength part of the visible spectrum). Different wavelengths bounce off air molecules, or pass around air molecules without bouncing off, depending upon their wavelength, whether it is larger or smaller than the size of an air molecule. As a result the atmosphere alters the light that passes through it. Blue is scattered, making the sky appear blue, while leaving more of the longer wavelengths in the sunlight that reaches the Earth, giving it a warm golden color. This phenomenon is officially known as Rayleigh Scattering.
What color is the Visible spectrum wavelength of 750 nanometers?
Blue
Why is the color blue a color?
Blue is part of the colour spectrum, with a wavelength of about 475 nm.
What is the smallest wavelength of light?
The shortest wavelength of visible light is the wavelength of the last color you can see on the blue end of the rainbow or spectrum.
What color is the light spectrum with a wavelength of 450 to 420 nanometers?
Blue light
What is the scientific notation for finding the wavelength of blue light?
To find the wavelength of blue light, simply look at an electromagnetic spectrum, specifically the visible light portion. Blue light corresponds to a wavelength of around 475 nm.
As you move from the blue region of the electromagnetic spectrum to the red region of the electromagnetic spectrum what happens to the frequency of the light?
colour blue ------> red frequency drops, wavelength increases, because speed remains constant and speed=frequency*wavelength
Which color of visible light has the highest frequency?
blueee!!
What is lowest depth of a wavelength?
Light from the red end of the spectrum penetrates deep water better than light from the blue end of the spectrum. Evidence: Algae that live in deeper water have chlorophylls with absorbance peaks in the infra-red part of the spectrum.
White light can be separated into spectrum of colors because each color of light?
Has a different wavelength and energy. At the red end of the spectrum the wavelength is longer and frequency is lower, it will be less easily refracted than light towards the blue end of the spectrum, which is higher in frequency and has a shorter wavelength. The separation of the colours is called dispersion.
What wavelength does chlorophyll a absorb the most energy?
Chlorophyll a absorbs the most light (energy) in the blue- violet spectrum
3 Which wavelength of light is the shortest?
The blue end of the spectrum has shorter wavelengths than the red end.Whatever color is the last one your eyes can see at the blue end, that's the visible color with the shortest wavelength.
What color of light in the visible spectrum has the highest frequency?
The highest frequency/shortest wavelength of visible light isthe last color you can see on the blue end of the spectrum.
