because when light hits the prism the prism scatters the light in all directions there for you can see the rainbow
To separate the rays in a light beam and make a rainbow, you can use a prism or water droplets in the atmosphere. When light enters a prism, it is refracted at different angles depending on its wavelength, causing the different colors in the light spectrum to separate. Similarly, when sunlight passes through water droplets in the air, it is refracted and dispersed, creating a rainbow.
When Light(White Light) enters a prism through one of its face, due to difference in the refractive indexes of the medium i.e. air and the glass of which the prism is made up of, and the difference in the wavelengths of difference colors of which white light is made up of the light scatters and a SPECTRUM of different colors is observed. However the scattering of light may depend upon the angle of incidence also as if the prism is kept at an angle where the angle is incidence is greater than the critical angle of prism, the light may undergo TOTAL INTERNAL REFLECTION i.e. TIR..!!
Depending on the positioning of the prism, it will merge the rainbow back together or spread the eight rays even further. Using this tactic, it is possible to concentrate light even further inwards, depending on how you orient the prism. If an edge is facing the light, it will spread. If a face is facing the light, it will converge.
the light travels though the prism and is reflected on an object and the light is to go though all side/faces of the prism and the light is to change colorTo make this more clear: The light goes through and separates into different colors of the rainbow.
It refracts the light, basically taking the light beam apart and spreading it out to see all the visible colors in the light spectrum. Water does the same thing and that is how rainbows are made.

it will make a rainbow on the wall
the light reflects of the droplets like a prism and bend the rays of light to make a rainbow
White light, if passing through a prism, can make a rainbow via the optics phenomenon known as dispersion.

It separates the light by their wavelengths to make a color spectrum, and gives one a rainbow.

The water acts like a prism and white light shines through it, it makes a rainbow.
The moisture droplets in the air refract the light like a prism. This happens with millions of droplets, and depending on the angle at which you observe it, you see a rainbow.

A laser beam consists of a single frequency of light, therefore it cannot form a spectrum or rainbow.
Rainbow is made by: Light+water (droplets).Make real a rainbow yourself:Constant and fine shower of water (perhaps from a hose)a sunny dayMake a fake rainbow:Quite powerful torchGlass prism
