Percy l. Spencer had a choclate bar and when he turned on the magnetron and he felt a sizzling sensation and when he took out the choclate bar it melted complrtely
The volume of a microwave oven is typically measured in liters (L) or cubic feet (ft³).
The equivalent of one liter is 1000 milliliters.
No. 4.1 L is equal to 4100 mLTo convert from L to mL, you multiply the given value by 1000.

William L. Potts invented the first manually operated traffic light in Detroit, Michigan in 1920. He installed the traffic light at the intersection of Woodward and Michigan Avenues.
Percy L. Spencer invented the Microwave Oven
in 1945 .
to heat food
January 24, 1950
The microwave oven was invented by Percy Spencer, an American engineer working for Raytheon Corporation, in 1945. While experimenting with radar equipment, he discovered that microwave radiation had the ability to cook food quickly. This led to the development of the first microwave oven for commercial use.

microwave oven
If I'm not mistaken, the first microwave unit was built in the Motorola labs while experimenting on a new radio technology. The person working on the device got too close to the magnetron (the microwave tube) and had a Hershey bar which he was holding in his back pocket and then the choclate bar melted melt. That also was a clue that microwave ovens were possible.
No one discovered microwave ovens. They were first used in 1837 or so when a high school dropout discovered that microwaves emitted heat (or something). He noticed this as he reached into his pocket for his chocolate bar, only to find it had melted. He had been working in a lab full of microwaves (the radiation type, not the oven). The next time, he brought an egg and some popcorn. The egg exploded, having being cooked from the inside. Later, popcorn was popping everywhere. That was the discovery of microwaves being a potential cheaper use of ovens. Sorry, but that answer is totally i correct. People didn't know how to harness electricity in 1837... it was 1945, and the person whose chocolate bar melted was Percy Spencer of Raytheon (who only went to grammar school). He realized that microwaves heated the chocolate, then tried popcorn. Heat applied for a patent for heating food. After that, he and others at Raytheon worked at designing an oven that could be used for cooking. The result was something that looked like a 5 foot high refrigerator and weighed 600 - 700 pounds. It was in the 1960's that the first table top units were produced.
