How Microwaves Work
To understand the implications of standing in front of an open microwave, it’s crucial to grasp how microwaves work. Microwave ovens use a type of non-ionizing radiation called microwaves to heat and cook food. These microwaves are generated by a device called a magnetron within the oven. When you press the start button, the magnetron converts electrical energy into microwave energy, which is then directed into the cooking compartment. The microwaves penetrate the food and cause the water molecules in the food to rotate back and forth at the same frequency as the microwaves. This movement generates heat through dielectric heating, effectively cooking the food.
