Which characteristic is used to measure the amount of light radiated by a star?
A. size
B. color
C. luminosity
D. temperature

Asked by blg64549

Answer (2)

The amount of light radiated by a star is measured by its luminosity , which quantifies the total energy emitted by the star. While related characteristics like size, color, and temperature can influence luminosity, they do not measure it directly. Luminosity is essential for comparing the brightness and energy output of different stars. ;
