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

The measure of the amount of light radiated by a star is called luminosity. It quantifies the total energy output of a star and is considered the primary characteristic for this measurement. Characteristics such as size, color, and temperature can influence luminosity but do not measure it directly. ;

The amount of light radiated by a star is measured by its luminosity, which reflects the total energy emitted. Size, color, and temperature influence luminosity but do not measure it directly. The relationship between temperature and luminosity can be explained by the Stefan-Boltzmann Law.
