Why are there only seven colors in white light?

1.	Why are there only seven colors in white light?
Answer» ANSWER: You must have seen when light passes through a prism it disperse and the PHENOMENON is called dispersion and we see the spectrum of seven Colors but it has got all the RADIATION but our eyes can see only those frequencies and hence only 7 colors.
