Radio waves and microwaves are very important to us for communication. ... And for heating up left over pizza ... They are both on the long wavelength end of the Electromagnetic
Radio wavesWood protectionThermal pest control with hot air is widely accepted as an alternative to chemical methods. However, it requires relatively long treatment times owing to the low thermal conductivity of wood. Direct dielectric heating that applies radio waves or microwaves has the advantage ...
