Question

Why are blue stars the hottest when we associate blue with cold temperatures?

In: Physics

Answer 1

We associate blue with cold because we’re used to seeing water ice or cold people who are bluish because there is very little blood flushing their skin. But the energy in light follows the spectrum and doesn’t care about the impressions we get from the tiny experience we have. Red, orange, yellow, green, blue, violet.
