Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter, which are used in mobile phones, cooking food, and radar systems. Microwaves have frequencies between radio and infrared waves and are able to penetrate materials to be absorbed by water molecules, generating heat. While microwaves are useful in cooking and communication technologies, living cells can be damaged by their heating effect if overexposed, requiring caution in their use.

6. 1) Microwaves have wavelengths which are
used to transmit information to
satellites.
2) Microwaves cause water molecules to
vibrate, making substances hot.
How is it used?
7. - Living cells can be damaged/killed by
the heating waves.
- Skin cells can be burned.
- Causes cataracts in your eyes.
