Which of the following frequencies falls in the range of rf waves used by commercial radio broadcasting stations a 60 hz b 6000 hz c 600000 hz d 6000000 hz?

The third choice on the list ... 600,000 Hz ... is the same as 600 KHz.
That's the "600" (or "60") displayed near low end of the AM radio dial.
The first two items on the list are not used for radio communication:
-- 60 Hz is the frequency of the AC power that comes out of the
household electrical outlet (in North America).
-- 6,000 Hz is in the audible range. Current at that frequency is present
in every earphone, loudspeaker, and local telephone line.
The last item on the list ... 6,000,000 Hz or 6 MHz ... is in the international
broadcast bands. It can be tuned on any "short wave" radio.

∙ 10y agoThe correct one is 600000 Hz (600KHz) which is in the AM radio band.

Commercial AM radio stations (in the USA) operate on carrier frequencies spaced every 10 KHz between 550 KHz and 1.65 MHz.
Commercial FM radio stations operate on carrier frequencies spaced every 200 KHz between 88.1 MHz and 107.9 MHz.
Commercial analog TV used to start at 54 MHz and get 6 MHz for each channel, with gaps for other services. Since the forced mass exodus to all-digital TV in June '09, we don't really know where all of the TV frequencies are now.

∙ 9y agoA). 60 Hz is essentially useless for communication. That's the frequency of the electric utility grid in North America, so every line on every pole, and every extension cord in every house and factory, is radiating a bit of RF energy at 60 Hz ... not a frequency conducive to attempts to communicate.
B). 6,000 Hz is very difficult for communication. The wavelength at that frequency is about 50 km (roughly 31 miles), so it would be almost impossible to construct efficient antennas, whether for transmitting or receiving. There's no radio communication here.
C). 600,000 Hz. (600 KHz) This frequency is the '600' that appears near the left end of the dial on everyone's AM radio receiver.
D). 6,000,000 Hz (6 MHz) This frequency isn't where you find 'commercial' broadcasting, but it IS where you find a large amount of international 'short wave' broadcast activity.

What is the frequency used by most commercial radio stations?
In the USA: All commercial AM stations are assigned frequencies in the band 550-1620 KHz, in increments of 10 KHz. All commercial FM stations are assigned frequencies in the band 88-108 MHz, in increments of 100 KHz (0.1 MHz).
What is the frequency band used by most commercial radio stations?
In the USA: All commercial AM stations are assigned frequencies in the band 550-1620 KHz, in increments of 10 KHz. All commercial FM stations are assigned frequencies in the band 88-108 MHz, in increments of 100 KHz (0.1 MHz).
Can you give the frequency for all radio stations?
Yes we can. At least for the commercial broadcast stations in the USA.AM stations:Carrier frequencies are at every 10 KHz, between 550 KHz and 1700 KHz.FM stations:Carrier frequencies are at every 0.2 MHz, between 88.1 MHz and 107.9 MHz.
What do broadcasting stations use to send their signals around the world?
Broadcasting stations use television satellites to send their signals around the world.
AM radio frequency?
An AM-modulated transmission can be operated on any radio frequency. In the USA, AM commercial broadcast stations are assigned carrier frequencies between 550 KHz and 1.7 MHz.
Which one of the following frequencies falls in the range of RF waves used by commercial radio broadcasting stations?
See page 101 of your study unit. In there you will find that radio frequencies used by commercial radio broadcasting stations range from about 550,000 Hz to 1,700,000 Hz.

What frequencies of RF waves are used by commercial radio broadcasting stations?
In the US, the AM broadcast band occupies 550 - 1,700 KHz, with assigned carrier frequencies spaced by 10 KHz. The FM broadcast band occupies 88 - 108 MHz, with assigned carrier frequencies spaced by 200 KHz (0.2 MHz) starting at 88.1 MHz.
What frequencies falls in the range of RF waves used by commercial radio broadcastings stations?
The frequency that falls in the range of RF waves used by commercial radio broadcasting stations is 3 kHz to 300 GHz. This is the frequency of radio waves and the alternating currents that carry them.
What is the frequencies in the range of RF waves used by commercial radio broadcasting stations?
Each country has different frequency bands allocated for AM and FM radio. In the U.S. AM takes up the range from 535KHz to 1605KHz. FM radio takes 88.0MHz to 108.0MHz.Each radio station then receives a slice of that frequency band, regulated by the FCC. Each station is typically given a frequency far from all other stations. For example, three stations would be given the frequencies 93.3MHz, 94.5MHz and 96.1MHz. In theory, the stations could be closer (ie 94.3MHz, 94.5MHz and 94.7MHz) though this is rarely done because each station would then cause more interference to its neighbors.(The stations don't actually 'cause interference' to their neighbors. The weaknessis the ability of consumer-grade receivers to separate stations whose frequenciesare close together.)

What do broadcasting stations use to send their signals around the world?
Broadcasting stations use television satellites to send their signals around the world.
When you listen to a radio why are you able to hear only one station at a time rather then all stations at once?
Because different radio stations broadcast at different frequencies, and the radio tuner lets you decide which frequencies to listen to. Radio station owners have to buy the rights to use a particular frequency within a particular area. When you are driving sometimes you will hear two stations overlapping as you move out of the range of one station and into the range of another that is broadcasting on the same frequency.
What have television stations had to do for the switch to digital television?
They've had to switch their over the air broadcasting to all digital broadcasting.
AM radio frequency?
An AM-modulated transmission can be operated on any radio frequency. In the USA, AM commercial broadcast stations are assigned carrier frequencies between 550 KHz and 1.7 MHz.
