← ScienceWhich event occurs because of time dilation when identical atomic clocks at different gravitational potentials are compared?
A)Lower clock frequency at lower altitude✓
B)Higher clock frequency at lower altitude
C)Equal frequency despite altitude variance
D)No frequency shift; gravity is irrelevant
💡 Explanation
Lower altitude implies stronger gravitational potential; the equivalence principle dictates gravitational effects are similar to acceleration, which always causes time dilation; therefore the atomic clock ticks slower rather than faster, because of reduced spacetime curvature.
