Refraction index of any material depends upon the wavelength of the light. This fact can be used to resolve the light beam into the spectral components it consists of. One of the tools used for spectrum analysis of light is the glass prism. Let us consider and beam of the light propagating symmetrically to prism (see the figure). If a is the refractive angle of the prism, then we can find from the condition n = sin x0 / sin x = sin z / sin z0 that n = sin (a/2 + j/2) / sin ( a/2 ) (1) In practice the refraction index n depends upon the light wavelength l , so the angle j at which the prism refracts the light will depend upon the light wavelength too: D = dj / dl = (dj / dn)(dn / dl ) (2) Value dn / dl is called the dispersion of the material. This constant and refractive index n(l) characterize the basic optical properties of the material the prism is made of. Differentiating the formula (1) we can find the premultiplier in the equation (2). Really: dn / dj = cos (a /2 + j /2) / 2sin ( a /2 ) (3) and therefore (4) We can see from this formula that to achieve the maximal resolution of the prism on the wavelength we should use the materials with the maximal values of refraction index n and dispersion constant (dn / dl ).

you get your spectrum by placing a prism in front of a single ray of white light, then by putting another prism opposite it the light will then go through that prism and in the end you will end up back with your single ray of light that you started with.
yes
In optics, a prism refracts incoming light.
It may do if you threw it a t one.
The cause of seeing an oval prism light in both eyes could be a seizure. Alternatively, it could be aphasia. It is best to consult an eye doctor.
the prism can obtained coloured of light in prism due to disperion of light
When ordinary visible light shines on a prism.
because when light hits the prism the prism scatters the light in all directions there for you can see the rainbow
I believe that you are talking about a prism, and the process where the light is broken up in to its constituent parts is called dispersion
It is named after the type of prism used in the instrument. A constant deviation prism has the property that the angle between light entering the prism (the incident light) and light exiting the prism (the emergent light) is always the same, no matter what the angle of the incident light to the prism.
As the light passes through the prism, the resulting effect is called a 'refraction'. In other words, the light enters from one side of the prism and is then 'redirected' at a right angle as it exits the prism.
red light is monochromatic light and if it shines on a prism its still red light pass through the prism, not 'rainbow' color.
A device for separating light into different colors is know as a ?
reflection
Light could bend when it enters a prism. A prism is a transparent object such as glass.
The refractive index of violet light is most in a glass prism and is the least for the red light. So violet light is most refracted in the glass prism.
Light is refracted and reflected by a (glass) prism Light is refracted and reflected by a raindrop
