Radio waves. Low frequency.
Radio waves are the type of electromagnetic wave that carries television and radio signals. They have longer wavelengths than microwaves and shorter wavelengths than infrared waves.
Radio waves
because on the em spectrum, radio waves are the lowest. if a tv used a higher raadioactive source like uv and you were exposed to it to much (by watching to much tv) you could get cancer and die unfortunately.
Radio waves are the longest lengthwise.
Microwaves. They give off microwaves! Also light bulbs (visible EM), heating coils (infra-red EM), and ovens (infra-red EM). Also radios and TVs receive radio waves, garage-door openers generate and transmit radio waves, blow-driers irradiate the air passing through them with infrared (heat) waves, smart and dumb cellphones all send and receive radio waves, laptops on wireless home wi-fi send and receive radio waves, and their screens generate and radiate visible light waves which make it a lot easier for us to see what they're computing.
Cell Phones depend on The EM Radio Waves to Work. By: And
They have different wavelength.
Radio waves have the longest wavelength in the electromagnetic spectrum (EM), and are pure energy, they have no mass.
