Which consequence results when gravitational forces on a light clock at differing altitudes vary, according to the principle of equivalence?

A)Time appears slower below
B)Space is uniformly isotropic
C)Photons gain orbital velocity
D)Planck’s constant is relativistically invariant

💡 Explanation

When gravitational forces affect a light clock at different altitudes, time appears slower at lower altitude, because of gravitational time dilation; this is related to general equivalence, therefore time slows down rather than remaining constant, because a strong field is equivalent to acceleration.
