Diathermy is defined as the therapeutic use of what to heat deep tissues?

Explanation:
Diathermy heats deep tissues by delivering high-frequency electromagnetic energy. These waves penetrate through soft tissues and are absorbed, turning into heat inside the body, which allows warming of deeper structures rather than just the surface. This mechanism distinguishes diathermy from ultrasound, which uses mechanical (sound) waves to produce heat, and from cryogenic cooling, which lowers tissue temperature. High-frequency electromagnetic energy (radiofrequency or microwave ranges) is the key factor enabling therapeutic deep heating.
