Tesla High Frequency is characterized by:

High rate of oscillation or vibration
Cool air application
Deep tissue massage
Ultraviolet radiation

The correct answer is: High rate of oscillation or vibration

Tesla High Frequency is a form of electrotherapy that involves high-frequency oscillation of currents on the skin. It produces a mild electrical stimulation and warmth, which can promote blood flow and stimulate cellular activity. Option B is incorrect because cool air application does not produce the same effects. Option C is incorrect because deep tissue massage is a manual technique, not a form of electrotherapy. Option D is incorrect because ultraviolet radiation is a form of light therapy, not a high-frequency current.
