If you see a red-hot star, you can be certain that that its peak intensity is in the ingrared region. Why is this? And if you see a violet-hot star, you can be certaiin its peak intensity is in the ultraviolet range. Why is this?

• Physics -

The human eye is not very sensitive to red or violet. So if you see red or violet as the predominant spectrum, its intensity is very high.
