Alternating current produces EM Wave.
What determines the frequency(or wave length) of an EM wave related to current or voltage?

Pretty much.sawer said:So 60 hz ac generates 60 hz Em wave. Is that all?

Is there any formula?

sawer said:I'm sorry. I think I wasn't clear.
I didn't ask about the frequency of electricity.
Electric field generates the Electromagnetic wave and that wave has a frequency.
Em wave's frequency can be changed and this is why there is an EM spectrum.
I want to learn what effects the frequency of EM wave?
For example; 60HZ electricity can generates EM wave, so how can we relate the frequency of electricity with EM wave's frequency? Or is it related?
What are the parameters that are related with frequency of EM wave?

davenn said:The frequency of the AC signal, and therefore any radiated EM wave is determined by the components of the oscillator or generator.
The formula is in the working out the values of the tuned circuit/speed of rotation of the generator
That is regardless of if its an audio oscillator or a RF oscillator

The frequency of an EM wave can be adjusted by changing the source of the wave. This can be done by using a different type of antenna or changing the electrical current in the circuit.
No, the frequency of an EM wave cannot be adjusted manually. It can only be changed by altering the source of the wave.
The frequency and wavelength of an EM wave are inversely proportional. This means that as the frequency increases, the wavelength decreases and vice versa.
Adjusting the frequency of an EM wave can have various applications. It can be used in communication systems to transmit signals over long distances, in medical imaging to produce clearer images, and in scientific research to study different properties of EM waves.
Yes, there is a limit to the frequency range of an EM wave. It is determined by the properties of the source and the medium through which the wave is travelling. Going beyond this limit can result in a loss of signal or distortion of the wave.
