Put this in a short sentence in your own words How do microwave ovens cook your food? Microwaves oscillate at frequencies that are just right to shake and manipulate certain molecules in food, particularly water molecules. Because these molecules respond to effect of a passing microwave, they can absorb its energy. This means that microwave ovens work very differently from conventional ovens, where the presence of high temperature (i. e moving ) molecules transfer heat through collisions with the molecules in your food
