Identify two ways in which astronomers can use an H-R diagram?
Classify stars and to understand how stars change over time
What are the two main properties that astonomers use to classify stars?
The surface temperature and the absolute magnitude, which is the brightness of the star when viewed from a standard distance of 10 parsecs.
What are the two properties of sound waves that you use to classify different sounds?
The two properties are :- Pitch & Amplitude
What is a gigantism?
One of two groups of stars on the Hertzsprung -Russell diagram that have a different set of properties than the main sequence stars; bright, low-temperature giant stars that are enormously bright for their temperature.
What is a red gigant?
One of two groups of stars on the Hertzsprung -Russell diagram that have a different set of properties than the main sequence stars; bright, low-temperature giant stars that are enormously bright for their temperature.
What are the two ways you can classify stars?
The two ways are by their surface temperature (spectrum) and by their absolute magnitude (intrinsic brightness). The HR diagram has spectrum along the horizontal axis and absolute magnitude along the vertical axis. Each star occupies a point in the HR diagram.
Are Name two categories used to classify properties matter?

What is a H-R diagram and what two characteristics of stars are compared on it?
It is a diagram on which stars are plotted according to their absolute magnitudes (or luminosities) against their stellar classifications (or effective temperatures).
What are two properties of light that you can show using a ray diagram?
brightness and size - yousaf
What two caracteristics of a star are plotted on the Hertzsprung Russell diagram?
Brightness and Temperature are the two characteristics plotted on the H-R diagram a diagram used to plot the absolute magnitude of stars and their temperatures
What two caracteristics of a star are plotted on the Hertzsprung-Russell diagram?
Brightness and Temperature are the two characteristics plotted on the H-R diagram a diagram used to plot the absolute magnitude of stars and their temperatures
What is another name for a plot of surface temperatures of stars against their absolute magnitude?
This type of diagram is often called a Hertzprung-Russell diagram after two astronomers.
