Why does a prism cause white light to separate into the spectrum?
Because different colours have different have speeds in a prism , as refractive index depends on speed of the object therefore different colours have different refractive indexes
Why is a prism able to separate the colors of white light?
A clear glass prism (and rain drops in the sky on a sunny day) are able to separate white light into the colours of the rainbow. The basic reason is that white light is reflected at different angles because of the different wavelengths.
A device that uses a prism or diffraction grating to separate light into its color components?
A device for separating light into different colors is know as a ?
What is an optical instrument that separates light entering it into components of wavelength?
A diffraction grating A prism, A spectrometer.
Can you separate white light?
Yes, very easily. A ray of white light can be split be shining it through a prism (triangular glass block) or a raindrop: both create a spectrum, or rainbow, of split up colours. This works because white light is made up from different colours of light that are all waves with different wavelengths/frequencies. This means that the colours are all refracted (bent) by different amounts when they go through the prism/drop, causing the ray of white light to split up into its components.

What is used to seporate colours and what it is called?
We use prism to separate the 7 colors of the white light,,this is called white light dispersion because each one has different wave length and different energy.
Why in some jurisdictions the traffic light colours have different shapes?
Traffic light colours have different shapes in order to inform the colour blind what colour the light is.
What is The spreading of light into its different colours?
Its a spectrum
How do different colors appear on CD?
When white light shines on the CD, the light is separated into seven colours, so different colours appear on the CD.

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 are some examples of light?
According to the range of frequency of emission light has different colours in different frequenies. Violet. Indigo, Blue, green,Yellow, Orange,Red are the main colours of light.
What explains why a prism separate white light into the colors of the rainbow?
Different colours travel at different velocity in a glass medium. Refractive index is defined as the ratio of the velocity of light in free space to that in medium. So refractive index becomes different for different colours. Now by Snell's law the refractive index is inversely proportional to the angle of refraction. Hence different colours get deviated at different angle of refraction. So the splitting of composite white light into its constituent colours has become possible. If these again fall at a parallel surface as in the case of a glass slab the colours split would get combined back and emerge as white light. But we have prism where the two refracting surfaces are at inclined and further splitting takes place and hence dispersion.
