The condition under which a microwave oven heats up a food item containing water molecules most efficiently is
Options
- Athe frequency of the microwave must match the resonant frequency of the water molecules
- Bthe frequency of the microwave has no relation with natural frequency of water molecules
- Cmicrowave are heat waves, so always produce heating
- Dinfrared waves produce heating in a microwave oven
Correct answer
A. the frequency of the microwave must match the resonant frequency of the water molecules
Step-by-step solution
It is electromagnetive wave, therefore the correct choice is (1).
