Correct Answer: D
Solution :
[d] Frequency band designation Given in the order of Frequency band> Designation > Typical service 3-30 kHz > Very low frequency (VLF) > Navigation, sonar 30-300 kHz > Low frequency (LF) > Radio beacons, navigational aids 300-3,000 kHz > Medium frequency (MF) > AM broadcasting, marintime radio, Coast Guard communication, direction finding 3-30 MHz > High frequency (HF) >Telephone, telegraph, and facsimile; shortwave international broadcasting; amature radio; citizen's band; ship-to-coast and ship-to- aircraft communication 30-300MHz > Very high frequency (VHF) > Television, FM broadcast, air-traffic control, police, taxicab mobil radio, navigational aids 300-3,000MHz > Ultrahigh frequency (UHF)> Television, satellite communication, radiosonde, surveillance radar, navigational aids 3-30 GHz > Superhigh frequency (SHF) > Airborne radar, microwave links, common- carrier land mobile communication, satellite communication 30-300 GHz > Extreme high frequency (EHF) > Radar, experimental
