AM radio, FM radio, television, cellphones, GPS, and microwave ovens
all use radio waves that are longer than the ones used for RADAR.
All wavelengths used for communication are longer than all infrared, visible, ultraviolet, and X-ray wavelengths.
AM radio operates at 500-1500kHz, which translates to 600-200 m wavelengths. TV uses several non-contiguous frequency bands starting at 54 MHz which translates to wavelengths of 5.556 m and below. Clearly AM radio has much longer wavelengths.
No. Your cellphone, many TV stations, and the GPS satellites transmit wavelengths shorter than 1 meter. X-rays have wavelengths between 0.00000000001 and 0.00000001 meter. (1/100th of a nanometer to 10 nanometers)

The one with screen is the television, the other is the radio.

Radio, Telegraph, TV (rare), Telephone, Radar, & crude computers.
No. Radar waves are one category of radio waves. Think of all the radio waves that are all around you right now . . . AM radio, FM radio, police and fire radio, highway patrol radio, taxi radio, television picture and sound radio waves, cellphone radio waves, garage-door-opener radio waves, bluetooth radio waves, WiFi waves, microwaves ... and you can't see any of them ! Radar waves can easily be there in the group.
TV broadcast signals are in the VHF & UHF radio bands, shorter than most of the radio bands but longer than the microwave band.
Mainstream marketing is TV, Radio, Print (Newspaper, Magazine, etc.) Under the radar is unconventional; viral video is probably the best example.

Radar systems usually use wavelengths and are associated with digital signal processing. They consist of a transmitter, antenna receiver, switch, data recorder, processor, and display. Radar systems are used to track things including weather.
