mikrolaineteni
Mikrolaineteni is a term that refers to microwave ovens in Estonian. A microwave oven is a kitchen appliance that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This process causes polarized molecules within the food, primarily water, to rotate, generating thermal energy through dielectric heating. Microwave ovens are widely used for reheating leftovers, defrosting frozen foods, and cooking a variety of dishes. They are characterized by a magnetron tube that produces the microwaves, a waveguide to direct them into the cooking chamber, and a turntable to ensure even heating. Safety features are incorporated to prevent microwave leakage. The development of the microwave oven began in the mid-20th century, with commercial production starting in the late 1940s.
