Explain how radio frequency interference and electromagnetic interference issues are handled on audio cables including microphone cables?

Sensitive devices like microphones working at verylow level can and will pick extraneous signal from many sources solution is to shield the cable so the signal will be hard to influence a double shield scheme is desirable whereby the interference will be routed to ground

How are overtones created?
An overtone is a natural resonance or vibration frequency of a system. Systems described by overtones are often sound systems, for example, blown pipes or plucked strings. If such a system is excited, a number of sound frequencies may be produced, including a fundamental tone of given frequency. An integer multiple of the fundamental frequency is called a harmonic. The second overtone is not the second harmonic. (See related link "Calculations of Harmonics and Overtones from Fundamental Frequency")
How are radio waves xrays microwaves and the suns rays different?
Radio waves ... including microwaves ... and X-rays are different only in wavelength (frequency). The sun radiates all of them.
What note corresponds to a frequency of 60 hertz?
Assuming the frequency of Middle C to be 261.63 hertz, accurate to two decimal places, taking this two octaves down brings us to 65.41 hertz. Sending us down a further semitone gives us 65.41 x 1/21/12, which sends us to B, at a frequency of 61.74 hertz, accurate to two decimal places, the closest possible genuine note to a 60 hertz frequency. Effectively, this is the third B below middle C, including that which is a semitone below.
Are radio waves produced by lightning?
The radio does not cause lightning. The people from the office use tools to detect weather their is going to be lightning and then announce it.
How do you relate the frequency of length of vibrating string?
As the tension of a string increases the pitch increasesDirect RelationshipIf by pitch you mean a specific frequency change than this is a more relevant knowledge piece:The equation for the fundamental frequency of an ideal taut string is:f = √(TL/m)/2Lwheref is the frequency in Hertz (Hz)T is the string tension in Newtons (N)L is the length of the string in meters (m)m is the mass of the string in kilograms (kg)√(TL/m) is the square root of T times Ldivided by m (it is the square root of what is in the parentheses but not including the 2L)Source: http://www.school-for-champions.com/science/sound_string_equation.htm
Do microwaves have the highest frequency?
No. Several other electromagnetic waves - including visible light - have a higher frequency.
Which has the lowest frequency in the electromagnetic spectrum microwaves radio waves visible light or gamma rays?
Radio waves have the lowest frequency in all of the electromagnetic spectrum. The next higher frequency energy is microwave, visible light including ultraviolet, infrared, X-ray, then gamma ray
How can you shield yourself from extra low frequency electromagnetic radiation?
Every electromagnetic interference problem has three elements: a source, a victim and a coupling path. To stop electromagnetic interference, it is only necessary to eliminate or attenuate any one of these three elements. A good source of information concerning electromagnetic interference (including design guidelines) is the Clemson Vehicular Electronics Laboratory web site at http://www.cvel.clemson.edu. They have an electromagnetic compatibility section that has useful background information, design tools and design advice.
What do light waves of greater frequency have?
The meaning of a high frequency wave is a shorter wavelength.For electromagnetic waves in general (including light):* At greater frequencies, you get shorter wavelengths.* At greater frequencies, you get more energy per photon.
What is the relationship between the energy and wavelength of electromagnetic radiation?
Wavelength and frequency are inversely proportional. The higher the frequency, the shorter (lower) the wavelength. Energy is proportional to frequency, and higher frequency waves will have a higher energy. Mathematically, frequency = 1 divided by wavelength, or f = 1/λ Use the link below for more information, including a diagram or two to make things clearer.
What did I hear because I recorded silence in my attic and heard a whisper or growling when I played it back?
This is normal it is probably just radio interference this happens on most recorders if there is silence the microphone amplifies any sound including interference its nothing to be afraid of plus the closer you listen you may begin to hear things like whispers and growls this is just the mind trying to pick out voices or sounds that are familiar or in a relative frequency to our ears again this is all normal and not paranormal in any way
How do stars use frequencies?
The electromagnetic radiation (including light) have frequencies. Stars may also pulsate (get larger and smaller, and thus brighter and less bright) at a certain frequency.
What is radio frequency used for?
2.4GHz microwave, a band assigned for low power unlicensed users (including microwave cookers) that must tolerate interference from any other user of the band, even if the interference makes them inoperative. I think g is also allowed on 4.8GHz microwave.
What radio frequency is used for 802.11g?
2.4GHz microwave, a band assigned for low power unlicensed users (including microwave cookers) that must tolerate interference from any other user of the band, even if the interference makes them inoperative. I think g is also allowed on 4.8GHz microwave.
How do you make microphone in little alchemy?
Human+music, it get's you band, singer, and a bunch of instruments, including microphone
What type of EMR has the longest wavelength?
A photon is a fundamental or elementary particle and the carrier of the electromagnetic field. In this light (no pun intended) it can be applied to all electromagnetic energy, including radio waves. There wouldn't be a "lowest frequency" of electromagnetic radiation that was not photonic. ---- ...or if there was it would have a wavelength the size of the Universe : ) Couldn't carry a whole lot of data there...
Does cumulative frequency is the total of all class frequencies up to but not including the frequency of the present class?
No.
