Respuesta :
in the kitchen. micro-wave ovens: they use the heating properties of radiofrequencies: water molecules in the food are reheated by absorbing the energy generated by very powerful radiation in a confined space. induction hobs: they function using medium frequency magnetic fields that produce the heat needed for cooking.
Electromagnetic radiation is defined as the waves propagating through space and traveling in the electromagnetic field. The three objects that produce electromagnetic waves are:
- Microwaves
- Computer Screens
- Television
Electromagnetic radiations include infrared rays, gamma rays, microwaves, and radio waves. The household items that produce electromagnetic radiation are:
- Television produces electromagnetic waves through which television stations are broadcasted. The antennae on the television receive the signals in the form of electromagnetic radiation and display them on the television.
- Microwave consists of magnetron, which generates microwaves. These waves' wavelengths range from one meter to one millimeter.
- Computer screens also emit radiation. The frequency of radiation of laptop and computer screens ranges between 400 to 800 Hz.
Therefore, television, computer screens, and microwaves produce electromagnetic radiation.
