To heat the food containing water, the frequency of the microwaves used in microwave oven is
Options
- Aindependent of the resonant frequency of water molecules.
- Bequal to the resonant frequency of water molecules.
- C100 times the resonant frequency of water molecules.
- D1 100 times the resonant frequency of water molecules.
Correct answer
B. equal to the resonant frequency of water molecules.
Step-by-step solution
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.
