Best Answer

when white light shines through a prism it refracts it and seperates it into seven colours.

Answer

White light is made up of all the different colours mixed together. When the white light goes into the prism it slows down because glass is denser than air. The different colours have different frequencies and so are slowed down by different amounts.

As the colours slow down they also bend slightly, this is called refraction. This means that when they leave the prism they are travelling at different angles. As the colours are separated you see a rainbow line coming out of the prism, this is called a spectrum.

You can recombine the colours into white light using another prism at an opposite angle to the first one.

The colours are as followed in order-

Red, Orange,Yellow,Green,Blue,Indigo,Violet

The easiest way to remember is ROY G BIV. I remember it frome school.

That is a fail an easier way is roger of york gave battle in vein.

"White" light is actually a mixture of all frequencies of light from red to violet, red at the lowest visible frequency and violet the highest. When a thin beam of white light is fed into a prism, the low frequency of red light is refracted less than the higher frequency of violet light. The higher the frequency, the more refraction (or bending). Therefore, The white will be separated into the rainbow effect you see coming out of the other end.

What happens when a ray of light is shone at a prism, the light will bend causing it to refract and split into a rainbow effect. With this effect, you see seven different colors because as the white light passes through the prism, the wavelength changes.

I am assuming that "gass prisum" is meant to be glass prism.

If the red light is monochromatic (single frequency) then a narrow beam of light shone onto a glass prism will emerge from the prism as a narrow beam of red light whose path has been bent.


If, however, the red light is not monochromatic, it will be split up into the range of frequencies in the red part of the spectrum - in much the same way as white light is split up into the rainbow colours.

the light enters the prism, bounces back out and as it exits, the light is broken down.

What happens when light is shone through a prism?

It depends on the shape of the prism and the angle of incidence. For prism in the shape of an equilateral triangle the white light splits into the colours of the spectrum as red light is slowed down less than blue in glass, so the red light is bent less than the blue


What will happen the ray is shone at the prism?

when the ray is shone at the prism, refraction occurs and the light will split into it's original colour.


What is the break up of white light into seven colours?

It is the refraction of white light being shone through a glass prism, or a raindrop, that separates the white light into the colours of the rainbow.

Why does the spectrum appear when White light is shone into a prism?

because the prism splits the white light into all colors of visible light


What happens when light is shone at a prism?

It splits into the colours that make it up, so white light makes a rainbow, and different colours produce different results.


What happens when a ray shone at a glass block?

The white light splits into a spectrum.the original colors will appear. This is referred as REFRACTION.
