Description

The electronic oven is basically simple. A vacuum tube called a magnetron generates microwaves (high frequency radio waves) which actually do the cooking. When the magnetron is activated, it sends out microwaves via an electronic antenna. The waves are emitted inside the oven, pass through the food and bounce off the walls of the oven. As the waves pass through the food, they create friction by agitating the molecular structure of the food. This can be compared with what happens when you rub your hands together rapidly ... heat is created. The Federal Trade Commission assigns definite wave lengths for cooking electronically so the operation of the ovens will not interfere with radio or TV reception. Currently there are two cooking frequencies assigned ― 915 and 2450 megamillion cycles per second.
