mikrovågsvågor

Mikrovågsvågor, often shortened to mikrovågor, are a form of electromagnetic radiation that falls within the electromagnetic spectrum between radio waves and infrared radiation. They have wavelengths ranging from about one meter to one millimeter, and frequencies between 300 MHz (0.3 GHz) and 300 GHz. These waves are commonly used for telecommunications, including mobile phones and Wi-Fi, as well as in radar systems and microwave ovens for cooking.

The principle behind microwave ovens is their ability to efficiently heat water molecules. When microwaves interact with water, they cause the molecules to vibrate rapidly, generating heat through friction. This process is known as dielectric heating. While generally safe for their intended purposes, prolonged or intense exposure to high-power microwaves can pose health risks, though common household microwave ovens operate at levels considered safe. The generation of microwaves typically involves specialized electronic components such as magnetrons or klystrons. Their ability to penetrate many non-metallic materials makes them versatile for various applications, from heating food to transmitting data.
