It might be a Common knowledge that Light travels with different velocity in different mediums viz. Solid, Liquid or Gas.
This is mainly because of the fact that different mediums have different Optical Density and when Light enters any Specific medium a part of the incident light will in fact be scattered by the particles of that medium. This depends on the fact that how tightly the molecules or Dispersed Particles are held together which is highest in case of Solids and Least in case of Gases.
Now we have Understood that Light travels with varying velocities in any media. This property of Light is Known as 'Refraction'.
For example, a light ray will refract as it enters and leaves glass, Its wavelengthincreases or decreases.
Traveling of Light through Prism:A prism is a transparent solid usually made of glass or such transparent compounds bounded by three rectangular faces and two triangular faces.
So when a Polychromatic Ray of Light is passed through it, the different wavelengths of light suffer varying degree of refraction and Ultimately If a Screen is Placed behind the Prism the different constituent components of the light can be Obtained.
i.e., Polychromatic Light is divided into ----> V I B G Y O R
V= Violet
I= Indigo
B= Blue
G= Green
Y= Yellow
O= Orange
R= Red
Add a second prism to combine the light.
The first prism separates the light and the second prism combines the light.
by passing it through another prism that can convert light to combine
just put the second prism just in the opposite direction as of the prism

A prism seperates light into different colours, when White light passes through the spectrum giving you its colours, red,orange,yellow,green,blue,indigo and violet.
It uses the fact that refraction works differently for different frequencies - some frequencies refract more than others.
yes.
after the light passes through the prism, the light is technically still the same just separated into different energy levels or colors. if you want to achieve the "white" light that entered the prism again, you can place another prism in front of the colored light and it should combine and create the "white" light again.
The various frequencies are separated.
because the 7 colors which form the white light is separated as their speed is not the same in the prism.

With a prism. Light striking the prism is of different wavelenghts. These corrospond to the thickness of the wedge splitting the colors out of the source. They can be put back together with another prism.
This is normally done by passing it through a prism.
Refraction is the phenomenon causes colors of visible light to be separated by a prism.
