Describe how spectrum can be shown using a prism?
Refraction.In addition to refraction, a common prism demonstrates that different wavelengths of light travel at different velocities in the prism material. Hence the spreading out of the various colours.
Are there 5 colours in the visible spectrum of white light?
The 7 accepted colours of the rainbow are: Red, Orange, Yellow, Green, Blue, Indigo, Violet. A rainbow forms when sunlight, shinning through raindrops, is split into the main colours making up 'white' light.
Why are there seven colours in a rainbow?
Because "color" is an interaction between the visible light portion of the electromagnetic spectrum and the light sensitive parts of our eyes. Our eyes have evolved 4 different receptors--one each for Red, Green and Blue and another for violet. A rainbow actually contains millions of colors, but we have evolved to categorize most of the wavelengths in the visible spectrum as one of the primary colors and their combinations.
What spectrum does white light form?
when dispersed through a prism: Visible spectrum of light (rainbow) part of (very small fraction) electromagnets spectrum
Which type of spectrum is produced when light from the sun passes through a prism?
It is the spectrum of visible light, which has the colors of the rainbow.
What is white light shining through a prism spreads out to form this?
spectrum
The spreading of light waves into a spectrum results from?
White light is made up of many lights which have different properties. We say that there are seven colours of light. We see a spectrum when white light is passed through a glass prism. When the various colours pass out of the air and into the prism, they are bent at different angles. This happens again when the rays leave the glass and pass back into the air. That is when we see the almost magical spectrum.
Where you see a spectrum of colours?
If you pass white light through a prism, it will separate out into the individual colors of the visible spectrum.
What is the name givin to the range of colours prodused when a white light passes through a prism?
Spectrum. The order of colours is named as VIBGYOR
Why in an absorption spectrum the back ground is bright and the lines are dark?
Because it is an absorption spectrum. An absorption spectrum begins with a source of pure white light. This hits a prism which spreads it out into a spectrum and the result shows on a screen as a bright band of colours. If you put this into a glass case and seal it to the outside world, nothing changes. Now if blow a gas into the tank, the atoms in the gas absorb different wavelengths (colours) of light. The result you see is a normal spectrum of colours, but with one or more dark lines across it. This is because the atoms in the gas through which the white light is shining are absorbing some or all of various colours in the spectrum. What those colours are is absolutely characteristic and definitive of that particular gas. This is a very powerful technique for identifying elements which are present only in trace amounts. An interesting light on this is that the element Helium was first discovered not on earth, but on the sun by some dark lines in the sun's spectrum which did not belong to any known element.
What is the spectum?
White light is composed of many colours. When these colours combine, they look white. One way of showing that white light is composed of different colours is to make white light pass through a glass prism. This splits up the white light into its constituent colours. I f you hold a screen in its path, you will see a band of colours. This band of colours is called the spectrum. Since it is visible to human eyes, it is called the visible spectrum.

How do you obtain a spectrum by using a beam of energy waves?
In light you obtain a spectrum by passing the beam of white light through an object (a prism) which breaks the 'beam' up into it's constituent colours.
When white light is refracted through a prism different color emerge where do the different colors come from?
Type your answer here... OK. White light is made of the colours of the spectrum (Red, Orange, Yellow, Green, Blue, Indigo and Violet - these are the same as the colours of the rainbow). The reason you see these colours instead of wwhite when you shine white light through a prism is that the prism "bends" the light - which splits it into the colours of the spectrum. Red light is the longest, so it is bent the least, and Violet is the shortest - so it is bent the most. This is also how rainbows are made - the rain droplets act as prisms to disperse (split) the light into the colours of the spectrum.
