They can use a kind of glass/cristal named Prisma
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.
A prism.
A prism can be used for splitting light into its constituent colors, but scientists tend to use a more precise instrument called a spectrograph.
The prime colours of light are green, red and blue. Any other colour is a result of a mixture of these colours. The prime colours of light are different to the prime colours in art, so don't get confused!
It's "white light". When all colours of the rainbow are combined in their purest form (light), they create white light. All colours of the rainbow can be derived from the colours red, green and blue. These 3 colours are known as the RGB colour model (Red, Green, Blue). When these three colours are combined in their purest form, they also form white light
A dispersive prism can break light into its spectral colours, or the colours of the rainbow
diffraction grating prism
A single dimensional shape.
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.

A prism.
The device is a glass prism. A cross-section of a prism is an isosceles triangle.
Scientists can assess which elements are present in the star, by looking at the light it gives off and breaking this light down into the different colours that make up the total colour. They look at the spectrum given off. The different elements present in the star cause different light wavelengths (or colours) to be emitted.
A device for separating light into different colors is know as a ?
