How could you show that the colours of the spectrum combine to give white light?
In the spectrum of white light by a prism, the colour at the extreme end opposite to the base of prism is ______.
A glass prism is able to produce the spectrum when white light passes through it, but a glass slab doesn’t produce any spectrum. Explain why it is so.
