Also the amount of useful information that can be sent in a given period of time on such low frequency carriers is severely limited. The theoretical maximum bit rate on a 30Hz carrier is only 15 bits per second, not even 2 bytes per second (a typical typewriter can do at least 10 characters per second) and the practical maximum bit rate is of course lower, possibly only 3 to 5 bits per second.

But yes, radio waves of 30Hz and even lower can be transmitted.

AM radio signals are?

Amplitute Modulation signals. a modulation(mixing)method used in early radio transmissions.in many countries, radio transmissions below 30 Mhz,are still using this method.short wave,medium wave transmissions,and some extent of VHF transmissions are possible in this method.


What are Electromagnetic wave transmitted by a radio station called?

Radio stations that broadcast in the AM to FM range transmit EM waves known justly as radio waves (EM waves with frequencies from 30 KHz to 300 MHz, or wavelengths from 10 km to 1 m).


An Aircraft vhf communicaion radio is operated at 30 Mhz and how to calculate its wave length?

The frequency can't be 30 Mhz 30 Mhz is a ham radio frequency but to calculate the wavelength, devide 300 by the frequency in Mhz that will give you 10 meters (300/ƒ)


The speed of all electromagnetic waves through space is 300000000 miles per second What is the frequency of a radio wave that has a wavelength of 10 miles?

With the digits written in the question, the unit should be "meters per second", not miles.A radio wave with a wavelength of 10 meters has a frequency of (300,000,000 / 10) = 30 MHz.300,000,000 meters = 186,282 milesA radio wave with a wavelength of 10 miles has a frequency of (186,282 / 10) = 18,628 Hz.


Radio waves broadcast by a radio sta-tion strike your radio and your ear.Infer whether the human ear can hear radio waves.What evidence supports your con-clusion?

The human ear cannot hear radio waves because they are electromagnetic waves with frequencies typically ranging from about 30 kHz to 300 GHz, which are far below the audible range for humans (20 Hz to 20 kHz). While radio waves can be detected by radio receivers, the ear is designed to respond only to sound waves, which are mechanical vibrations transmitted through air or other media. Therefore, the fact that we require a radio receiver to convert radio waves into audible sound supports the conclusion that the ear cannot directly hear radio waves.

What is the frequency in broadcasting?

Depending primarily on its frequency,radio wave may travel from the tranmitting to the receiving aerial in a number of ways.The most important of these are : 1. Ground waves (or Surface waves):they are useful for low frequencies of below 1000 KHz . 2. Sky waves: the transmission of radio waves in the frequency range of 3 to 30 MHz. 3.Direct waves( or line-of sight waves):At frequency above 30 MHz ,radio transmission cannot be carried out by ground wave or sky wave.


What is one example of a low frequency wave?

One example of a low frequency wave is a radio wave, which has a frequency range typically between 30 Hz and 300 GHz. These waves are used for broadcasting radio and television signals, as well as for wireless communication.


Does drm radio receive short wave?

Yes, standard DRM is transmitted on long-, medium and also shortwaves up to 30 MHz. The DRM+ extension is transmitted above this frequency and into television VHF band III in its latest iteration. There is more on the DRM system on e.g. www.drm.org (official homepage), www.drmRADIO.dk (listener- and broadcaster-oriented homepage) or www.drmradio.co.uk (more technically oriented homepage).

How is a radio wave different from the colors?

Radio waves have a much longer wavelength. Colours or visible light have a wavelength of less than 1 thousandth of a millimetre, while radio waves can have wavelengths up to 30 kilometres. They are all types of electromagnetic wave whose existence was predicted by James Clerk Maxwell.


Why do radio waves with extremely long wavelengths such as ELF radio waves need huge antennas?

Answer: An antenna is a tuned circuit, so it have to be tuned to the wavelength of the signal that it will transmit. If the antenna is not tuned properly some of the transmitted power will be feed back to the transmitter and will damage the output stage, SWR (Standing Wave Ratio) is very important, that is the ratio between the power that is transmitted by the antenna and the power that is fed back to the transmitter a zero is ideal but not always possible.The lower the frequency the longer the wave length and a 1/4 wave length is the minimum length that will give one a good SWR. The formula to use when one design a antenna is 300/frequency in MHz, if the frequency is 30 MHz then it is 300/30 = 10 Meter divide it by 4 to get the length of the 1/4 wave antenna that is 2,5 meters.Note: The antenna have to be multiples of a 1/4 wavelength like 1/2 wave or full wave, a 5/8 length can be used but it will need a L/C circuit at the input of the antenna to tune it to the frequency.


Which would be hotter 35 degrees Celsius or 35 degrees Fahrenheit and why?

30 C. is a heat wave, but 30 F is just below freezing. So 30 C is hotter by far.

What is the frequency range for radio wave?

We generate and detect radio waves for purposes of communication, cooking, andscientific investigation, in the frequency range of roughly 30 KHz to 300 GHz,corresponding to wavelengths between 10,000 meters and 1 millimeter.
