What do pure colors do when they pass through a prism?
Pure colors separate into different wavelengths of light when they pass through a prism, resulting in a spectrum of colors. This phenomenon is called dispersion, where each color is refracted at a slightly different angle due to its unique wavelength.
Why does LED light not separate after passing through a prism?
LED light does not separate into colors after passing through a prism because LED light is typically composed of a single color or narrow range of wavelengths. Unlike white light, which contains a broad spectrum of colors that can be split by a prism, the emission spectrum of LED light is limited, resulting in no observable separation.
How can a pure spectrum be obtained?
when a beam of white light coming from a slit passes through a prism it splits up into seven colors which is obtained on screen.in practice following conditions should be satisfied to obtain a pure spectrum-- the slit should be narrow-then only a few rays will fall on prism and overlapping of colors will be reduced.- the rays falling on the prism should be parallel-all the rays will be incident on the prism at the same angle and rays of same color will emerge parallel to one another which maybe focused at one point.-the rays emerging from the prism should be focused on the screen by an achromatic convex lens-the prism should be placed in minimum deviation position w.r.t. the mean ray and the refracting edge of the prism should be parallel to the slit-focusing of different colors would be the sharpest.all these requirements are fulfilled in a spectrometer.
Can electricity pass through oil?
yes,but in this case refraction takes place.
Is the spectrum obtained by an equilateral glass prism pure or impure?
The spectrum is impure, that is, the bands of light will merge together, with no clearly defined boundary.

When white light lite is dispersed by a prism a spectrum is obtained on a screen if you pass a beam of pure blue light through a prism what would you see on the screen?
We see different colours of light because of their different frequencies. White light is actually lots of different frequencies, you see a spectrum because when light diffracts (slows down and changes direction) each frequency diffracts by a different amount, some bend more than others. Because blue light is only one frequency it will not produce a spectrum, so all the light bends by the same ammount.
What colors refract out of red?
Red is a pure color, no other colors can come out of it when reflected through a prism.
How does a prism form visible light?
It is split/dispersed further for exactly the same reasons as one prism splits white light. Isaac Newton's classic experiment conducted during the plague year of 1665 in England was arranged as follows He closed the wooden shutters in a room during a sunny day and made a hole in the shutters to allow a shaft of sunlight to enter the darkened room. On a pedestal in the centre of the room he arranged a glass prism to refract the white sunlight into a spectrum of colours which were displayed on the whitewashed wall. He then blocked all the other colours except red light emitted from the first prism by using a sheet of wood. The red light from the first prism was then directed towards a second glass prism to see if more colours or white light would be generated. He found that the red light was further refracted and no other colours were produced. He thus determined that sunlight was composed of the 7 colours of the spectrum. It is not at all easy to take a spectrum and recombine it through a prism to make white light. It can be done by mixing red,blue,and green light from separate pure light sources of these colours. This is how colour television works and is called additive mixing .This is different to mixing paint pigments together, this is called subtractive mixing.
Why does the white light split into different colors when it passes through the prism?
1) White light is a mixture of different colors in the first place. 2) These colors have different indices of refraction - they bend at slightly different angles when they pass from air to glass.
Why is dialysis tubing not submerged in pure water?
The tubing is permeable; itallows water to pass through the tube wall.
What color cannot be made by mixing any other color?
These are colours that cannot be created through the mixing of other colours. They are colours in their own right. The three primary colours are RED, YELLOW and BLUE.
What is complementary colors?
Two colours are complementary if lights of those colours add to make pure white light. Complementary colours are not the same as complementary pigments (or paints).
Does chocolate have artificial colours in it?
no! it is made of pure cacao beans, milk, and sugar!
How did isac newton prove white light was composed of many colours?
It was already known that, when white light went through a prism, the light that came out was multi-colored. This meant either (1) the white light was made up of light of different colors or (2) when going through a prism, the white light had become contaminated, in the same way that clear water is colored by contaminants. Newtown showed that the multi-colored light could be re-combined into pure white light by going through a second prism. If idea (2) was correct, the light should have gotten MORE contaminated, and been MORE colorful. If (1) was correct, the light would re-combine into white light. When the experiment found that white light resulted from a second prism, idea (1) was shown to be correct.
