← ScienceWhich mechanism causes increased X-ray photon frequency passing near a magnetar?
A)Gravitational redshift energy conservation redshift
B)Synchrotron radiation particle acceleration
C)Gravitational blueshift spacetime curvature✓
D)Compton scattering inelastic collisions
💡 Explanation
Gravitational blueshift increases observed photon frequency because spacetime curvature near the magnetar affects photon energy during their passage, therefore frequency increases rather than a scattering effect or synchrotron radiation.
