← ScienceWhich outcome occurs to photon trajectories near neutron stars?
A)Gravitational lensing and spectral redshift✓
B)Increased propagation speed locally
C)Blueshift occurs via Doppler effect
D)No effect, paths remains rectilinear
💡 Explanation
The immense gravitational field causes spacetime curvature; photons follow geodesics, resulting in gravitational lensing and frequency shift. Therefore, lensing and redshift happen rather than faster speed; blueshift requires motion towards the source.
