Question

Which type of waves do not reveal information about stars

Answer 1

Answer:

The spectrum of a star is composed mainly of thermal radiation that produces a continuous spectrum. The star emits light over the entire electromagnetic spectrum, from the gamma rays to radio waves. However, stars do not emit the same amount of energy at all wavelengths.

The peak emission of their thermal radiation (the continuum peak in the spectrum above) comes at a wavelength determined by the star's surface temperature — the hotter the star, the bluer the continuum peak.
