Q What Are Microwaves? Ans Microwaves Are Very High Frequency Waves That Operate at 2450 Mhz. At frequencies of 2.45 Ghz, MWs are absorbed by water, sugar and fat molecules and converted into atomic motion. At these frequencies, MW are not absorbed by plastics, ceramics etc. and reflected by metals Q How Do Microwaves cook ? 1) In a Microwave oven, a Magnetron tube emits the MWs. 2) These Microwaves pass through the food. 3) The water molecules in the food begin to oscillate. 4)The oscillation generates heat energy due to friction. 5) The heat generated hence cooks the food particles nearby. Comparision Conventional Gas Vs Microwave Owen CONVENTIONAL GAS 1) Layer-by-layer, Outside to inside. 2) Spoils the kitchen wall with sprinkling of oil. 3) Separate utensils for cooking & serving. 4) More usage of Oil/Ghee. 5) More time consuming & tiring. 6) Nutritional Value of the food is lost due to longer cooking. 7) Installation Cost...
