It has been recognized for hundreds of years that sure components impart characteristic colours to a flame - a fact crucial to the coloured fireworks that we take pleasure in.

Copper, for instance, gives a inexperienced color, whereas sodium offers a yellow colour. It is actually attainable to establish elements by the cautious examination of such coloured flames. The light is split up right into a spectrum utilizing a prism or diffraction grating in an instrument called a spectroscope. Fairly than seeing a steady rainbow of colours, a collection of sharp coloured strains is formed.
