To heat the food containing water, the frequency of the microwaves used in microwave oven is
- A independent of the resonant frequency of water molecules.
- B equal to the resonant frequency of water molecules.
- C 100 times the resonant frequency of water molecules.
- D \(\frac{1}{100}\) times the resonant frequency of water molecules.
Answer & Solution
Correct Answer
(B) equal to the resonant frequency of water molecules.
Step-by-step Solution
Detailed explanation
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.
