The microwave oven was invented in 1946 by an engineer Percy Spencer but the invention itself was accidental involving chance, coincidence and imagination.

Percy Spenser who was working in the Raytheon Corporation on a project related to radars happened to stand near a magnetron, a device that emits microwave radiations, with a bar of chocolate in his pocket and noticed after some time that it had melted.

Further experiments with popcorn and eggs confirmed his suspicions that the microwave radiations emitted by the magnetron were somehow able to raise the temperature of the food placed near it and hence as a result could be used effectively for cooking purposes.

After initial experiments a microwave was built at Raytheon, but it was at first used only for defrosting purposes and also was quite large in size. Later in 1967 Amana, a division of Raytheon introduced the domestic microwave oven in the market which slowly but surely became popular as its price decreased mainly due to its unmatched speed of cooking.

This was the first prototype of the modern day microwave oven eventually becoming one of the most common of all kitchen appliances and changing food habits on a revolutionary level.

On 8th October, 1945, Percy Spencer invented the microwave with building magnetrons for radar sets. It was the item when he was working on an active radar set and at the point of time there was an ice cream in his pocket which began to melt. It was due to the microwaves that the ice cream melted. So the company built the first microwave in the year 1947 and named it Radarange. This microwave was 6 feet tall (1.8m) and it weighed almost 340 kgs (750 pounds). It was water-cooled and created 3000 watts, which is about three times the sum of energy produced by microwave ovens today.

With this invention the first thing that was cooked in the microwave was popcorn and the second was an egg.

Dr. Percy Lebaron Spencer was the inventor of the microwave oven in 1946. He was an engineer working with the Raytheon Corporation.

One day he was testing a magnetron, which was then a new vacuum tube. He had a bar of candy in his pocket. During his test, he noticed that the candy melted. This inspired Dr. Spencer to attempt another experiment, and this time, he used some popcorn kernels near the magnetron. He stood a little further away from the tube and looked on closely, beaming proudly at his new invention, while the kernels of popcorn sputtered, cracked and popped all over the place in his laboratory.

He conducted the third experiment using an egg, which promptly quaked. The tremors caused the yoke of the egg to splash all over the amazed scientist's face, but it definitely created a revolutionary appliance that no modern-day kitchen can be run without.

The development of the microwave oven was initiated by a discovery that was made by Dr. Percy Spencer. Dr. Spencer was in the process of doing research related to radars. The discovery occurred around 1946. He was testing a magnetron when he made his discovery. During his tests, Dr. Spencer found that a candy bar that had been in his pocket had melted. This event grabbed the engineer's interest. He then decided to perform another experiment to study this phenomenon. In this experiment, he placed some popcorn kernels near the magnetron and waited to see what would happen. The popcorn kernels began to pop around the magnetron and inside his lab. It was at this moment that Dr. Spencer knew that he was on to something. This spawned more research in the usage of microwave energy in cooking food. This would eventually lead to the invention of the first microwave in 1947.

October 8th, 1945 by Percy Spencer while they were testing vacuum tubes (magnetrons) and the candy bar in his pocket melted. He tested more experiments with this and tried popcorn kernels. Percy Spencer stared in awe as the kernels began to pop. He then fashioned a metal box, and fed energy into it. The energy was trapped, causing a bigger electromagnetic field, which made the temperature of the food rise rapidly.

October 8th, 1945. He was touring one of his laboratories at the Raytheon Company. He stopped in front of a magnetron,the power tube that drives a radar set. He felt a sudden and strange sensation, Spencer noticed that the chocolate bar in his pocket had begun to melt. He bought for popcorn kernels and set them next to the magnetron and watched as the kernels popped into white fluff.

If you are asking about microwave oven then it is invented by Percy Spencer in the year 1945. But if you want to know about the microwave (rays) then this question is same as "who invented electricity". Microwave energy is a natural phenomenon that happens when electric current passes by a conductor. Microwaves are a type of electromagnetic energy that is just like the sunlight and radio waves. So it is not invested not created it is already there and is discovered by James Clerk Maxwell in the year 1864.

Microwaves are electromagnetic waves with wavelengths from 1 mm to 1 m.
The existence of electromagnetic waves was predicted in 1864 by James
Maxwell. Hertz was the first person to demonstrate the existence of
electromagnetic waves in 1888. In 1894, Bose demonstrated the use of high frequency waves by generating microwaves to explode gunpowder and ring a bell at a distance.
