An electronic microwave oven (denshi renji in Japanese) is a kitchen appliance that uses microwaves (a form of electromagnetic radiation) to heat and cook food. It works by agitating water molecules within food, causing them to vibrate and produce heat, which cooks the food quickly. Microwaves are commonly used for reheating leftovers, defrosting frozen food, and cooking a variety of dishes.
History
↓↓
The microwave oven is an appliance that cooks or heats food using microwave radiation.
Its development began during World War II when Percy Spencer discovered that microwaves from radar equipment could heat food in 1945.
The first commercial microwave ovens were introduced in 1947 by Raytheon, but they were large and expensive, mainly for industrial or restaurant use.
By the 1960s and 1970s, smaller, more affordable microwave ovens became available for home kitchens.
Technological improvements over time added features like turntables, timers, and defrost settings.
Today, microwave ovens are standard household appliances worldwide, valued for convenience, speed, and versatility in cooking and reheating food.
