What is the Hertzsprung-Russel Diagram?
A map which tells the approximate location of stars in the Milky Way galaxy and their distance from Earth.
A table that alphabetically lists stars by name and includes dates of when the star was first charted.
A chart which organizes stars into categories based on the amount of Hydrogen they burn.
A graph used to classify stars according to their luminosity, color, temperature, and stage.
Luminosity is...
a stars core temperature.
how far the star is.
what color the star is.
how much light a star gives off.
when the frequency is higher what happens to the wavelength?
the wavelength gets longer
The wavelength gets shorter
the wavelength doesn't change
I have no idea
Redshift wavelength
doesn't change
stays the same
Gets longer/increases
gets shorter/decreases
Why can the apparent magnitude be inaccurate?
It doesn't exist
It may not be brighter compared to another star but instead just closer
It only shows the brightness of stars too far away for humans to detect
the scale is messed up
