When a ray of light is shone onto a prism, the light ray enters the prism and bends or refracts due to the change in speed as it moves from air to the denser prism material. Inside the prism, the ray undergoes total internal reflection at the surfaces, causing it to reflect and refract, creating a spectrum of colors known as dispersion.

What happens when you shine a green light onto cyan paper?
When a green light is shone onto cyan paper, the paper will absorb some of the green light and reflect the rest. Since cyan is a combination of green and blue, the green light will combine with the reflected blue light from the paper, making it appear brighter and more vibrant.
What happens when red light is shone onto a wall?
Any object that has light shone on it would appear in a particular color because the said object absorbs all the other colors of the spectrum and reflects one single color. when the light itself consists of a single color, the color of the object gets modified because the reflected light contains the color of the light and then part that is reflected. For ex, the wall in the question would appear red if the light is only one wavelength but would appear as a combination of red and its own natural color if the light is a combination of different wavelengths.
What happens when a ray of light is shone at a glass prism?
when white light shines through a prism it refracts it and seperates it into seven colours.AnswerWhite 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,VioletThe 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.Edited by 29206. OH YEAH
What happens when white light is shone onto a coloured object?
The object reflects the colour(s) you see and absorbs the rest. This is why black objects get hotter in the sun than white objects. The white 'colour' reflects much more energy (especially infra-red) whilst the black object absorbs more energy (especially infra-red).
How do you compare reflection refraction and dispersion?
You can compare it by saying that each of them occur when a light transfers through one meduim to another. That's one way of explaining it.That is incorrect :( It happens when light is shone onto or through a different medium. Reflection happens when light is shone ONTO a mirror, you cant shine light THROUGH a mirror.
What would a red object look like shone onto a white light?
red
What happens when you shine a green light onto cyan paper?
When a green light is shone onto cyan paper, the paper will absorb some of the green light and reflect the rest. Since cyan is a combination of green and blue, the green light will combine with the reflected blue light from the paper, making it appear brighter and more vibrant.
How can you make a spectrum?
you get a prism glass block and a thin ray of light shining onto the prism and rotate the prism till you see the spectrum

What happens when you shine a light ray onto a mirror?
it reflects
What happes when red and green light are reflect onto a piece of paper?
When red and green lights are shone onto a white piece of paper, the paper appears yellow. This is because red and green light mix to create yellow light when they are combined. The paper reflects the yellow light back to our eyes, making it appear yellow.
What affect does a different colored light bulb have on a prism?
A prism will split light into its component colors. If a colored light is used, there will be less colors in the split light. A beam from a red light for instance will have very little blue or green light in it so you will not get the full spectrum from the prism.
What happens when you shine a light ray onto a ray box?
It is reflected
What would a green object look like shone onto a yellow light?
When shining a green object onto a yellow light, the green object would absorb most of the yellow light while reflecting the green wavelengths. This would make the green object appear even brighter and more vibrant due to the contrast created by the yellow light.
