= HOW THE TV USE ELECTROMAGNETIC RADIATION? = IT USES RADIO WAVES TV WAVES-TO CONVERT AND TRANSFORM INTO SOUND AND IMAGES

NOTES:
How the TV use electromagnetic radiation the TV use to convert and transform into sound an images. The radio waves receives the particles the particles unit to make pictures and sound and pictures use waves of amplitude and sound use waves of frequency modulation.
 * TV radio with pictures
 * Radio waves carry signal for the picture and sound
 * Radio waves are charged particles moving
 * TV receives the particles unit to make a picture and sound
 * Pictures use waves of amplitude and sound use waves of frequency modulation

= How does the appliance you chose effect humans with their levels of electromagnetic radiation? = Radio waves from TV are not dangerous for you because the frequency is low and wavelength long. The hospitals have problems with the medical machines for the TV stations because the radio waves go in the machines. X-rays are more dangerous than radio waves.
