Every visible star is an example of emitted light, regardless of
how bright it seems.
Several invisible ones are too, even though there are external
reasons why they're invisible to us.
Spectroscopic analysis of the light emitted by the star.

Stellar spectra are graphs or visual representations of the intensity of light emitted by a star at different wavelengths. They provide information about the star's temperature, chemical composition, and motion towards or away from Earth. Studying stellar spectra is crucial for understanding the properties and evolution of stars.
I call it star light. Some more erudite folks might refer to it as stellar electromagnetic radiation.
The light from a star eight light years away will take eight years to reach Earth.
The spectrum is a kind of analysis of the light emitted by a star.
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
Ultra violet radiation has a shorter wavelength than visible light; this is true regardless of whether it is a star or any other source that is emitting it.

If the bright star is located farther away from Earth than the less bright star, it will appear dimmer due to the inverse square law of light intensity. The amount of light reaching Earth decreases with distance, so a closer, less bright star can appear brighter than a further, brighter star.

Light is a form of energy.
The outermost layer of a star is the photosphere. It is the visible surface of the star where most of the light is emitted.

Studying light is one part of astronomy. Things like the speed of light, how it travels, the spectrum of light are all things that are used in studying astronomy. Studying light emitted from a star can tell us all sorts of things about it, like how far away it is and how bright it really is.
