It's an electromagnetic wave used for treatment purposes with wavelength between infra-red rays and short wave diathermic waves.
The heat energy obtained from the wave is used for giving relief to the patient.
Treatment Settings
Micro-wave diathermy waves used for treatment is of Wave length - 12.25 cm
Frequency - 2,450 cycles/sec
Production of Waves
The waves are obtained by heating special type of valve called Magnetron. The output is carried to a small aerial and microwaves are emitted.
