An H-R diagram can be made by plotting
A)Luminosity versus color
B)Spectral class versus distance
C)Luminosity versus magnitude
D)Temperature versus distance

Question

Quizplus · Accepted Answer

An H-R diagram, also known as a Hertzsprung-Russell diagram, is a graph that plots the luminosity of stars against their spectral color or temperature. Therefore, choice A is the best option, as it represents the correct parameters for an H-R diagram. Choice B (spectral class versus distance) does not include the necessary data about luminosity, while choice C (luminosity versus magnitude) includes two measurements of brightness, which is not ideal. Choice D (temperature versus distance) also does not include the necessary data about luminosity.
