Introduction

Cooking with Microwave Energy

Microwaves are a form of high frequency electromagnetic waves (approx 12cm wavelength) similar to those used by a

radio. Electricity is converted into microwave energy by the magnetron tube. The microwaves travel from the magnetron

tube to the oven cavity where they are reflected, transmitted or absorbed.
