A dispersive prism can break light into its spectral colours, or the colours of the rainbow
No exactly the contrary, white light is made up of light of all the colours of the rainbow. And you need to take that literally. The rainbow has these colours because rain acts as a prism and breaks the white light of the sun apart in the colours it is made up of. Because monochromatic means 'of one and the same colour', white light is not monochromatic. LASER light is always monochromatic: all particles have exactly the same wavelength (colour)

White light is composed of many colours. When these colours combine, they look white. One way of showing that white light is composed of different colours is to make white light pass through a glass prism. This splits up the white light into its constituent colours. I f you hold a screen in its path, you will see a band of colours. This band of colours is called the spectrum. Since it is visible to human eyes, it is called the visible spectrum.

The device is a glass prism. A cross-section of a prism is an isosceles triangle.

They can use a kind of glass/cristal named Prisma

Light appears white, however it is made up of different colours, which when put together make white light. These colours can be seen if you direct light through a prism. At the right angle the light is split up into the colours (rainbow).

It is the refraction of white light being shone through a glass prism, or a raindrop, that separates the white light into the colours of the rainbow.
