The effects are more important at the high frequency end.

Work Step by Step

A high-frequency photon has more energy and momentum than a low-energy photon. For a light of a certain intensity or energy, there are fewer photons when the light is high-frequency, so the graininess of the light, i.e., the quantum effects, are more readily observed.
