Which effect causes increased molecular vibrational frequency in a gravitational redshift experiment demonstrating the equivalence principle?

💡 Explanation

Gravitational time dilation causes increased molecular vibrational frequency because a clock at lower gravitational potential runs slower; therefore, the observed frequency increases relative to one at higher potential, rather than other quantum or classical alternatives.
