Why is white light regarded composition of seven colors?
White light is composed of a spectrum of colors because when white light passes through a prism, it is separated into different wavelengths, each corresponding to a different color. Sir Isaac Newton discovered this in the 17th century, showing that visible light is made up of seven colors: red, orange, yellow, green, blue, indigo, and violet, which collectively form the rainbow spectrum.
What are the colors of light other than the seven colors?
white!
Why is the white light regarded as a composition of seven colors?
White light is a composition of many more colors than seven. The presence in white light if any color at all can be demonstrated as follows: -- Mix a chemical dye that absorbs every color of light except the one you want to detect. Saturate a clear, transparent plastic sheet with the dye, and sandwich the sheet between clear layers of glass, forming what is known as an optical "filter". -- Direct a beam of white light at one side of the filter. Recall that the chemical dye absorbs every color of light except for the narrow band of wavelength which it has been designed to pass. -- Observe that light with the selected wavelength ("color") shines forth from the other side of the filter, demonstrating that it was present in the white light. Such filters can actually be constructed, with very narrow "passband".
Which scientist discovered that when light passes through a prism it splits into the seven colors that are colors of the rainbow?
Isaac Newton discovered that when light passes through a prism, it splits into the seven colors of the rainbow. This phenomenon is known as the dispersion of light.
Is artificial light also made of seven colours?
Depends on the source. Ordinary(incandescent) light bulbs have a spectra that's very similar to that of the sun, while fluorescents and LEDs in particular tend to be much more narrow and contain fewer colours.
What splits white light into seven colors?
A prism splits white light into seven colors by refracting (bending) different wavelengths at different angles due to the varying speeds of light in different media. This separation of colors is known as dispersion, with each color representing a different wavelength of light in the visible spectrum.
Which scientist discovered that when light passes through a prism it splits into the seven colors that's are colors of the rainbow?
Newton
What happens when all the seven colours of the spectrum combine together?
When all seven colors of the spectrum combine together, they create white light. This is because white light is a combination of all the colors in the visible spectrum.
Are there only seven colors of light?
No, there are actually infinitely many colors of light. The colors that we see are a small portion of the electromagnetic spectrum, with each color corresponding to a different wavelength of light. The visible spectrum consists of colors from red to violet, but there are many other colors that are outside of our visible range such as ultraviolet and infrared light.
