And, the answer for the the question is :
Explanation:
Percy Spencer, an American physicist, came up with the idea for the first microwave oven in 1945. However, it took a few decades for Spencer’s innovation to develop into the kitchen essential that we know and use today. The earliest models of microwave ovens may weigh up to 750 pounds and cost up to $5,000. As they shrunk in size and became more inexpensive, their popularity increased, and today, microwaves can be found in 90 percent of homes across the United States.
The microwave oven, a common appliance found in kitchens around the world, was first invented in the 1940s. The microwave oven revolutionized the way we cook and heat food, providing a fast and convenient way to prepare meals.
The first microwave oven was invented in 1945 by Percy Spencer, an engineer working for the Raytheon Corporation. Spencer was working on a radar system when he noticed that a candy bar in his pocket had melted. He realized that the radar waves from the system had caused the candy bar to heat up, and he began to experiment with using these waves to heat food.
Spencer’s first microwave oven was called the Radarange, and it was large, expensive, and primarily used in commercial kitchens. However, over time, the technology improved, and the microwave oven became smaller, more affordable, and more widely available.
The microwave oven works by using microwaves, a type of electromagnetic radiation, to heat food. The microwaves are generated by a device called a magnetron, which is located inside the oven. The microwaves are then directed into the oven and absorbed by the food, causing the water molecules in the food to vibrate and heat up.
The microwave oven quickly became a popular appliance in households around the world, providing a fast and convenient way to cook and heat food. The microwave oven’s popularity was driven by its speed, convenience, and energy efficiency, with many people using it to cook everything from popcorn to full meals.
Over time, the microwave oven has evolved and improved, with new features such as convection cooking and sensor technology making it even more versatile and convenient. The microwave oven has also played a significant role in the development of modern convenience foods, with many pre-packaged meals and snacks designed specifically for microwave cooking.
the invention of the microwave oven in the 1940s revolutionized the way we cook and heat food. The microwave oven’s speed, convenience, and energy efficiency have made it a popular appliance in households around the world, and it has played a significant role in the development of modern convenience foods. While the microwave oven has faced some criticism over the years, particularly regarding its impact on the nutritional value of food, it remains a popular and widely used appliance in kitchens around the world.
