How do microwave enable water to be heated in ovens?

Microwave ovens heat food by generating microwaves, which are a form of electromagnetic radiation with a frequency between 300 MHz and 300 GHz. Microwaves have a shorter wavelength than radio waves but a longer wavelength than infrared radiation.

When microwaves interact with water molecules, they cause them to vibrate. This vibration creates friction, which generates heat. The heat generated by the microwaves is what cooks the food.

Microwave ovens are designed to allow microwaves to pass through the walls of the oven and interact with the food inside. The food is placed on a turntable so that it is evenly heated by the microwaves.

Microwave ovens are a convenient way to heat food quickly. However, it is important to use them safely. Microwaves can cause burns, so it is important to use caution when handling hot food.
