← ScienceWhich outcome occurs when gravitational potential increases significantly near massive objects?
A)Time dilation increases for external observers
B)Observed frequency decreases upon redshift✓
C)Spacetime curvature decreases proportionally outward
D)Energy emission remains unexpectedly unaffected
💡 Explanation
Observed frequency decreases because gravitational redshift, related to the principle of equivalence, lowers EM-wave frequencies; therefore, frequencies shift redward rather than remaining constant because a higher gravitational potential lowers observed frequencies.
