The condition under which a microwave oven heats up a food item containing water molecules most efficiently is

Question

YESPYQ · Accepted Answer

Correct answer: c) the frequency of the microwaves must match the resonant frequency of the water molecules. In a microwave oven, the frequency of the microwaves matches with the resonant frequency of water molecules so that the maximum heat can be transferred to food in most efficient way. Thus, the frequency of the microwaves must match the resonant frequency of the water molecules.
