A microwave oven is a type of oven that uses microwaves to heat up food. Microwaves are a type of electromagnetic wave that is sandwiched between radio wave and infrared radiation on the electromagnetic spectrum and their frequencies range between 300 MHz (0.3 GHz) and 300 GHz.
These ovens, excluding the microwave oven are known as conventional ovens. Convection ovens are actually ovens similar to the original ones with an extra feature, fans. The only major difference between the conventional ovens and convection ovens are the fans. Convection ovens are also powered by gas or electricity. The fans allow the heat provided by the gas burners or electric coils to circulate throughout the enclosed space.
