How Do Microwaves Work?
Microwaves work by using microwaves (hence the name) to heat and cook food. The microwave oven contains a magnetron, which is the component that generates the microwaves. These microwaves are then directed into the oven cavity, also known as the cooking chamber.
The Process:
When you turn on the microwave oven and set the desired cooking time and power level, the magnetron produces electromagnetic waves with a wavelength of approximately 12.2 centimeters. These waves are then emitted into the oven cavity, where they bounce off the reflective metal walls. The microwaves are absorbed by the food, causing water molecules in the food to vibrate and produce heat. This heat then cooks or reheats the food.
The Safety Measures:
It’s important to note that microwaves are designed to heat food, not the containers they are placed in. Heat-resistant glass and microwave-safe plastic containers allow the microwaves to pass through them, while metal containers reflect microwaves and can cause sparks or fires. Therefore, it’s crucial to use microwave-safe cookware and avoid metal objects in the microwave oven.
