Light travels more slowly through 'optically dense' materials such as glass and diamond. The different wavelengths of light also move at different speeds in such materials, the blue light moves more slowly than the red light part of the spectrum, so all of the different colours that make up white light can be separated out when the white light enters the material at an angle. The blue light will bend more than the faster red light.
The bands of color that make up white light when combined are known as the visible light spectrum. They can be seen by the human eye when put through a prism.
It separates the light by their wavelengths to make a color spectrum, and gives one a rainbow.

Spectrum
light is white. if you mix the colors of the rainbow you get white. A prism separates the colors, showing a rainbow.
white light travelled through the prism when bands of color emerge.It observed that each band of color refracted at a different angle.Which concluded that the prism was not the source of colors. That different colors much have been present already in white light.
White light is composed from all the colours shown in a rainbow. The facets on a diamond acts like a prism and separates the white light into a flash of rainbow colours.
