GENERAL KNOWLEDGE

Detailed explanation-1: -We bake or heat food using a microwave oven which uses electromagnetic radiation to heat food. The microwaves radiations are reflected by metals, they are absorbed by food and they pass through plastic, glass, paper etc. These properties of microwaves make it suitable for cooking.

Detailed explanation-2: -The name Microwave is derived from the energy used to cook the food, microwaves, which pass through the cells and molecules of the food, the frequency of the waves causes the water molecules to vibrate, this movement generates heat. These microwaves are produced by a device called a magnetron within the microwave oven.

Detailed explanation-3: -Despite the potential for near-instant snack food, the first commercial Radarange microwave ovens unveiled by Raytheon in 1946 were intended for use in restaurants (as in the photo at top, which shows a prototype called the “Raydarange”) and for reheating meals on airplanes.
