← ScienceWhich measurement shifts when stellar mass curves spacetime?
A)Observed light frequency✓
B)Absolute star luminosity
C)Core fusion rate
D)Stellar chemical profile
💡 Explanation
Gravitational redshift alters perceived spectra; because photons lose energy escaping distorted spacetime, the observed frequency decreases due to the wavelength increase; therefore a redshift is detected rather than changes to source luminosity or core processes.
