Infrared radiation is long wavelength radiation given out by stars.
It is a consequence of something called blackbody radiation. Any object that is not at absolute zero emits electromagnetic radiation. The higher the temperature the cooler At temperatures we usually fin on Earth that radiation is in the infrared range. Hot enough objects emit much of their radiation as visible light. The coolest stars emit mostly red light, which has the longest wavelength of visible light. The hottest stars are blue, as blue light has a shorter wavelength.
the shortest peak wavelength.
Eta Carinae is one of the hottest known stars, with a surface temperature of approximately 38000 Kelvins. According to Wien's displacement law, the peak radiation of Eta Carinae is 76 nanometers, which is far into the ultraviolet spectrum.
The hotter an object is the shorter the wavelength of light it emits as a shorter wavelength means more concentrated energy. Blue light has a shorter wavelength than most other colors, so the hottest stars are blue.
Frequency or wavelength is used in the spectrum of astronomical objects in order to identify which chemical elements are present in the stars.
Different chemicals emit and absorb light at various wavelengths. Astronomers can look at the wavelength of light coming from stars and determine which chemicals must be present.
blue stars are the hottest stars.
