Apart from this, the oven has a wave guide, turntable, and a timer switch. When we place the food inside the chamber and turn the timer switch on, it sends a command to the magnetron to send microwaves, as well as to the turn table to start turning. The microwaves of microwave ovens can heat foods containing polar molecules, such as water, as polar molecules are prone to the vibration effect caused by the microwaves. To heat the food evenly the microwave's turntable spins the food around.
