← ScienceWhich shift occurs when a gamma-ray passes a dense neutron star?
A)Gravitational redshift increases substantially✓
B)Wavelength becomes constant and stable
C)Frequency undergoes frame dragging
D)Spacetime lensing causes polarization
💡 Explanation
Increased gravity near a neutron star causes Gravitational redshift, because the strong gravitational field affects photon energy as perceived by a distant observer. The frequency decreases; therefore redshift increases rather than other spectral changes linked to different mechanisms.
