Question

To heat the food containing water, the frequency of the microwaves used in microwave oven is, independent of the resonant frequency of water molecules., equal to the resonant frequency of water molecules., 100 times the resonant frequency of water molecules., 100 1 ​ times the resonant frequency of water molecules.

MARKS App · Accepted Answer

In a microwave oven, the frequency of the microwave must match the resonant frequency of water maleculer. In this way the maximum heat can be transferred to food in most efficient way.
