The Tesla High Frequency Current is commonly known as which ray?

• A. Blue ray
• B. White ray
• C. Infrared ray
• D. Violet ray

Answer: (D)

The question tests what color glow the Tesla high-frequency current produces in its discharge. When high-frequency current flows through a glass-covered electrode with gas inside, the electrical discharge creates a visible violet light. This characteristic violet glow led to the term “violet ray” for the device, a common name in electrotherapy and skincare history. The other colors listed don’t match the typical visible glow of this current—infrared is not visible and blue or white rays aren’t the traditional description used for this device. So, the violet ray is the best answer.
