What is light spectrum?

Light spectrum is the rainbow band of colours produced when light is split into many parts. If you look at a certain colour and magnify in 100’s of times, you will see that it is actually white and our eyes make it to appear as it does. As you see the chart above, the more red it is, the more cooler the matter is. When it is very blue, it will be very hot. Because our sun is more red, there are more hotter stars than our sun.
