When pure colours pass through a prism they?
oiuio
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.
Why does LED light not separate after passing through a prism?
If the light is a pure color, just one frequency, then there is nothing to separate.
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.
What properties of laser light led to its use in light shows?
Lasers are directional and single, pure colors.

What colors refract out of red?
Red is a pure color, no other colors can come out of it when reflected through a prism.
Where do the colors come from when white light is shown is a prism?
White light is not "pure", in the sense that it is a mixture of different colors.White light is not "pure", in the sense that it is a mixture of different colors.White light is not "pure", in the sense that it is a mixture of different colors.White light is not "pure", in the sense that it is a mixture of different colors.

A beam of white light shines through a glass prism in a darkened room to produce the colors of white light How would the pattern on the screen change if a pure red filter were placed in the path?
The white light beam would possess no Red rays (photons having the energy of Red), after transiting through the pure-red-filter; to be neither refracted nor projected onto any screen.
Why is dialysis tubing not submerged in pure water?
The tubing is permeable; itallows water to pass through the tube wall.
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.
What are pure colors?
Blue, Red, and Yellow
What are facts about primary colors?
·Red, Blue, and Yellow ·Considered Pure Colors ·Combinations of the three colors make up all other colors
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.
What is example of a insulator?
things that don't allow electricity or heat to pass through them. Example: Bakelite(a kind of plastic),dry air pure water,etc
