Not so. Here are the reasons why:
1) If you must know, anything from 1 - 20 hz is part of neuro-science since it has something to do with our brains. Scientists have been playing with the idea of being able to fuse technology with our brains like for reasons such as helping the handicapped/disabled people use a computer without having to use their disabled arms or the elderly being too slow and old to move anything so using their brain to move a mouse on the computer to do things is relevant.
2) Amplifying it just makes the signal stronger. Therefore the disabled do not need to be too close to the computer or have their wireless commands to the computer fade out as it travels along the way.
Besides anyway, i would like it if you could teach me how does a radio tuner work and whether it would be the same if i applied a Tank circuit to it? Because i remember someone telling me before that a radio tuner CAN tune between a start frequency and an end frequency to pick up FM or AM radio.
Thanks Bob
A radio tuner that receives medium wave AM and VHF FM doesn't tune to 20Hz.
An efficient antenna must be at least a quarter wavelength long.
The wavelength = 300 000 000/freq meters
Work out the antenna size for 0.57Hz
500mhz is very low. Do you mean 500MHz?
So I think the 300 000 000 meters/second is the speed of light.
Radio waves travel at the speed of light.
So then the equation is: wavelength = c / f , where wavelength is in meters, c is the speed of light 3.0x10^8 meters/second, and f is the frequency in hertz
So then the wavelength for 500KHZ would be (300 000 000 m/s )/ (500 000 (1/s)) = 600 m
So the wavelength for 500MHZ would be (300 000 000 m/s )/ (500 000 000 (1/s)) = 0.6 m = 60 cm
So then the wavelength for 5GHZ would (300 000 000 m/s )/ (5 000 000 000 (1/s)) = 0.06 m = 6 cm
So then the wavelength for 50 KHZ would (300 000 000 m/s )/ (50 000 (1/s)) = 6 000 m = 6 km
So then the wavelength for 5 KHZ would (300 000 000 m/s )/ (5 000 (1/s)) = 60 000 m = 60 km
So then the wavelength for 5 Hz would (300 000 000 m/s )/ (5 (1/s)) = 60 000 000 m =
60 000 km
So then the effective antenna length for 500 KHZ would be 150 meters long. Think antenna mast that has a blinking light on top so airplanes don't hit it. So the antenna mast helps receive signals for you so you don't have to have a 150 meter tall antenna in your backyard to receive 500 KHZ.
So then the effective antenna length for 500 MHZ would be 15 cm long. It can fit in your pocket, so cell phone uses UHF.
So then the effective antenna length for 5 GHZ would be 1.5 cm long. It can fit on a finger nail, so blue tooth, wireless game controllers, wireless printers, and WiFi use it.
So then the effective antenna length for 50 KHZ would be 1500 meters long = 1.5 km. Think antenna is as tall as Smokey Mountains in Northwest Georgia in USA. I think the U.S. Navy uses such low frequencies as ground penetrating and sea penetrating radio for communicating with submarines underwater and it runs antenna wire underground for several km in a rural area (in America we would call it a few miles, but since the moderators of this forum are from Australia, I have used km and using km also makes the math easier; dumb Americans that can't use metric so it makes the math much harder).
So then the effective antenna length for 5 Hz would be 15 000 km long. Think the antenna is the circumference of the Earth, read as its impossible only the Earth can resonate at that frequency.
So it is impossible to build a radio transmitter that transmits radio waves of 0.57 hertz. So having a long interval of time in between oscillations is the least of your problems when you would need to run an antenna wire around the circumference of the Earth.
