What type of waves does diathermy emit?

• A. X-rays
• B. Radio waves
• C. Infrared
• D. Ultraviolet

Answer: (B)

Diathermy heats tissue by using non-ionizing electromagnetic energy in the radiofrequency range. This energy penetrates deeper into tissues and is converted into heat, which is why diathermy can produce deeper heating than other modalities. X-rays and ultraviolet are high-energy forms of radiation and are used for imaging or skin effects, not for therapeutic heating. Infrared provides surface-level heating and doesn’t reach the deeper tissues that diathermy targets. Some diathermy devices use shortwave or microwave RF energy, all within the radiofrequency spectrum, to achieve that deeper heating effect.
