Answer

Ultraviolet light has more energy per photon.

Work Step by Step

The ejection of an electron depends on the interaction of one photon with an electron. For photons, E = hf, where E is the energy, h is Planck's constant, and f is the photon's vibrational frequency. UV light has a higher frequency than visible light, so ultraviolet photons are more effective at inducing the photoelectric effect. This is discussed on pages 585-587.
