Dispersion
by use of a 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.
Visible Spectrum
No, white light can also be separated into its component colors using a diffraction grating or refracting telescope.
Yes, a second glass prism can be used to recombine the spectral components that have been separated by the first prism. By carefully positioning the second prism, the dispersed light can be reversed and the original white light reconstituted. This process is known as prism recombination or prism recollection.
In optics, a prism refracts incoming light.
Visible Spectrum
When a ray of light is shone into a prism, the light ray refracts (bends) as it enters the prism, then undergoes further refraction as it exits the prism. This results in the separation of the light into its component colors, creating a rainbow-like spectrum.
