Roughly, the spectrum wavelengths are the speed of light divided by the frequency, c/f; 300M/400T=.75 micrometers for Red and 300M/800T=.375 micrometers for Violet..
These wavelengths are expressed usually as 750 nanometers and 375 Nanometers.

What happens when a substance absorbs light?
When a substance absorbs light the wavelengths that correspond to that color cannot be seen. Only colors that are reflected are visible.
What spectrum contains only specific wavelengths?
Continuous Spectrum
What wavelengths can the human eye see?
Human eye is sensitive to an approximate range of wave length of EM radiation from 380nm to 760nm. This portion of electromagnetic spectrum is identified as "visible light" These wavelengths roughly correspond to the colors violet, indigo, blue, green, yellow, orange, and red.
The electromagnetic waves with the longest wavelengths are?
Radio waves have the longest wavelengths in the electromagnetic spectrum
If an object absorbs all wavelengths of light except red what color will it appear?
The object will be red, due to the red light of the spectrum being reflected.
What color reflects wavelengths of the visible spectrum that hit it?
The color white reflects all wavelengths of the visible spectrum. That is why it is the brightest color.
What psychologist call the color of light?
Psychologists often refer to the color of light in terms of its wavelength on the electromagnetic spectrum. Different wavelengths correspond to different colors that humans perceive, ranging from shorter wavelengths like blue and violet to longer wavelengths like red and orange.
How does the color of the flame correspond to the distinct lines in its spectrum?
The color in the flame is the representation of a specific line in the spectrum.
What Bands of color created when white light is separated into different wavelengths?
Spectrum
What color does carotene reflect?
Carotene reflects orange wavelengths on the visible spectrum.
How astronomers measure stellar temperatures?
Stellar temperature can be measured by analysing the spectrum of light that stars emit; shorter wavelengths correspond to higher temperatures.
What is meant by the absorption spectrum of a pigment?
The absorption spectrum of pigment is the molecules response to light. The color of the pigment depends on the wavelengths of light the do not absorb.
Why is n2o3 colored?
Because its molecules contain differences between occupied and unoccupied energy levels of electrons that correspond in energy to part of the visible light spectrum. This causes the gas to absorb a noticeable fraction of some wavelenghts of visible lights while being transparent to others. The unabsorbed wavelengths of light correspond to the color of the gas.
How would one define color spectrum?
The color spectrum refers to the color produced when light is dispersed through a prism and is visible to the human eye. Typically, a human eye will respond to color occurring at wavelengths from 390 to 770nm.
What does a prism do to white light?
It separates the light by their wavelengths to make a color spectrum, and gives one a rainbow.
What does a prism to white light?
It separates the light by their wavelengths to make a color spectrum, and gives one a rainbow.
How are the continuous bright line spectrum and spectral lines similar?
In a continuous spectrum, you see every color in visible light from wavelengths around 380 nm to 780 nm. The bright light spectrum has only light at specific wavelengths, forming narrow regions of lights. This is characteristic of a particular substance, emitting these lights from its unique electron configuration. Light at specific wavelengths is emitted for different substances, but not a continuous rainbow.
