Question

Quizplus · Accepted Answer

Objects with temperatures in the millions of Kelvins give off most of their radiation in the X-ray part of the electromagnetic spectrum. This is because at higher temperatures, the electrons in the object are excited to higher energy levels, resulting in the emission of high-energy photons in the X-ray range.
