When pure colours pass through a prism they?
When pure colors pass through a prism, they are separated into their component wavelengths due to refraction, producing a spectrum of colors. This process reveals that white light is actually made up of a combination of different colors.
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.
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.
As the frequencies of the pure spectral colors increasewhat will happen to the wavelength of the colors?
As the frequencies of pure spectral colors increase, the wavelengths of the colors will decrease. This is because frequency and wavelength are inversely proportional in electromagnetic waves, according to the equation λν = c, where λ is the wavelength, ν is the frequency, and c is the speed of light.

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.
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.

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?
If a pure red filter is placed in the path of the white light, only the red component of the light would pass through, resulting in a pattern on the screen showing only shades of red. The other colors of the spectrum that were originally present would be blocked by the filter.

What are pure colors?
Blue, Red, and Yellow

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 phenomenon causes colors of visible light to be seperated by a prism?
Under a physical point of view, pure colors are different frequencies in the light. Generally a light beam is composed by a set of frequencies each of which with a different intensity. If a very concentrated pack of frequencies is clearly more powerful that color dominates and you see a colored light, otherwise you see a combination of colors that tends to white as far as the light spectrum (the set of present frequencies) is wide and all the frequencies have the same intensity. The refraction index of a material (glass for example) is a function of the frequency of the incoming light. Since the angle of refraction of a light beam by passing through the interface between different media depends on the two refraction indexes, beams of different frequencies are deflected at different angles by passing through the two interfaces air-glass and glass-air they encounter are deflected at different angles. If a light beam comprises a large number of frequencies, passing through the prism each frequency is deflected to its own angle. Thus the frequencies are divided and exits from the prism as different beams. The global effect is that a white beam (all the frequencies are present) exists from a prism as a sort of rainbow, where the colors (different frequencies) are directed in different direction and thus divided.
