In high frequency applications, the effect of more shallow insertion means that the current can concentrate more effectively in a specific area or tissue. When electrodes are inserted more superficially, the electrical field generated has a higher intensity at the surface level. This can lead to a more pronounced physiological response due to the increased local energy deposition.

High frequency currents, such as those used in electrotherapy, rely on the principle that the electrical energy can stimulate tissues in a specific manner. Shallow insertion optimizes the interaction between the current and the treated area, which can enhance the therapeutic benefits. Therefore, a more intense effect of the current is observed, leading to improved outcomes in terms of healing, pain relief, or other desired effects.

The other options do not accurately describe the scenario with high frequency applications, as they imply either a weak or negligible effect, which would not be the case when shallow insertion allows for better current concentration. Thus, the intensity of the current effect is indeed heightened with shallower insertion in these contexts.
