Q. What is microwave oven? How it works?
Microwave oven It is utilized to cook the food in a short time. When the oven is manage the microwaves are generated which in turn produce a non-uniform oscillating electric field. The water molecules in the food that are the electric dipoles are excited by an oscillating torque. Therefore few bonds in the water molecules are broken and heat energy is produced. This is utilized to cook food.
