What is the color spectrum represent?
If you let the light from the Sun pass through a prism, the result is a wonderful display of all the colors of the rainbow. Separating the combined colors of the Sun like this gives you a “spectrum”, which is just a measure of light emission as a function of energy (or wavelength, or frequency, which are all related).
What do the different Coloured lines in a line spectrum represent?
When atoms are excited they emit light of certain wavelengths which correspond to different colors. The emitted light can be observed as a series of colored lines with dark spaces in between; this series of colored lines is called a line or atomic spectra.
What do the lines in a light spectrum represent?
A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules.
What do the different colors of light correspond to?
Different wavelengths of light appear to our eyes as different colors. Shorter wavelengths appear blue or violet, and longer wavelengths appear red. The animation at the right shows a schematic drawing of a wave. The white line represents the wavelength.
What is the Order of the color spectrum?
The visible spectrum is always the same for a rainbow or the separated light from a prism. The order of colors is red, orange, yellow, green, blue, indigo, and violet. A fun way to remember this is by using the first letter in each color in order to spell out the name ROY G. BIV.
Which color has the lowest frequency?
Therefore violet has the highest frequency and the shortest wavelength of the visible colors of light. And red has the lowest frequency and the longest wavelength of the visible colors of light.
What are the colors of the visible spectrum?
The colors of the visible spectrum are red, orange, yellow, green, blue and violet. Color is a visual representation of electromagnetic radiation.
What are the colors of visible light?
The wavelengths of visible light are: Violet: 380-450 nm (688-789 THz frequency) Blue: 450-495 nm Green: 495-570 nm Yellow: 570-590 nm Orange: 590-620 nm Red: 620-750 nm (400-484 THz frequency)
