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

A

The frequency of the microwaves must match the resonant frequency of water molecules

B

The frequency of the microwaves has no relation with natural frequency of water molecules

C

Microwaves are heat waves, so always produce heating

D

Infra-red waves produce heating in a microwave oven

Text Solution

Verified by Experts

The correct Answer is:
A
In the presence of microwave water molecules oscillates the frequency of microwave and large heat is developed.
