The condition under which a microwave oven heats up a food item containing water molecules most efficiently is |
the frequency of the microwaves has no relation with natural frequency of water molecules. microwaves are heat waves, so always produce heating. infra-red waves produce heating in a microwave oven. the frequency of the microwaves must match the resonant frequency of the water molecules. |
the frequency of the microwaves must match the resonant frequency of the water molecules. |
Required condition : Frequency of microwaves = Resonant frequency of water molecules. |
