I don't think there is any upper limit, but the longest used in practice are in long wave radio transmission, this can be around 1500 meters

How do you find energy of an EM wave?
E=hv Where: E is energy h is plank's constant and v is frequency.
What gamma waves have?
Gamma waves have the shortest wavelength of any electromagnetic wave in the EM spectrum, the shortest wavelength means highest cyclic frequency, and highest intensity of any EM wave. (energy transferance by gamma waves is the strongest) *intensity is a measure of the height of the sine wave as opposed to to length, essentially more energy in a smaller crossectional area.
Why doesn't electromagnetic radiation run out of energy the further it travels. i.e. why doesn't the speed of electromagnetic radiation slow down the further it travels?
When you rigorously apply Maxwell's Equations to an accelerating charge, you find that an EM wave moves away from this charge. The E-field changes, resulting in a B-field; the B-field changes, resulting in an E-field. This process can be infinitely repeated with no loss of energy, as long as the EM wave travels through a vacuum. Thus, no loss in energy. You also find if you do the above that this wave ALWAYS propagates at the speed of light when in a vacuum -- no exceptions. That's just the way our Universe operates. The EM wave is NOT like a balling rolling on a floor. There is no frictional force on this wave that would cause a loss of energy or a slowing down.
What one of these is not particle proton neutron alpha gamma ray or a beta particle?
The gamma ray is not a particle but is just an EM wave that transmits energy.
What type of em radiation has shortest wavelength and most energy?
Gamma radiation
What type of EM radiation has the shortest wave length and the most energy?
gamma rays
What kind of EM wave has the lowest energy?
radio wave
How is wavelength of an EM wave related to its energy?
The shorter the wavelength of a wave, the higher its energy.
How em wave are generated from photon?
em wave is generated by photons which emitter the energy in the form of light
How is the frequency of an EM wave related to it's energy?
The higher the frequency of a wave, the higher its energy.
From Where does the energy carried by an EM wave come?
The electromagnetic (EM) spectrum is a name for different types of radiation. Most radiation comes from the sun. Want more info?
What type of light waves carry the most energy?
Gamma radiation is an extremely high frequency EM wave and is probably the common lightwave with the highest energy. Since energy is proportional to frequency, the highest energy wave would be that with the highest frequency.
How does the wavelength of a wave change when the frequency changes?
Usually with electromagnetic waves, the frequency and energy is opposite to the wavelength. An EM wave such as radiowaves have huge wavelengths, slow frequencies and small amounts of energy. An EM wave such as X-rays have tiny wavelengths, fast frequencies and large amounts of energy.
What happens when you increase electromagnetic wave?
To increase the intensity, if that's what you mean, more energy is required. That would also mean that the electromagnetic wave carries more energy.
How do you find energy of an EM wave?
E=hv Where: E is energy h is plank's constant and v is frequency.
Which of the EM waves has the highest energy?
The ones we call "gamma rays" do. Their frequency is so high that in the time of one cycle, light travels only a distance similar to the size of an atom.
What wave has sthe most light energy?
The sun wave has the most light energy, but most of you might not even know that there are more than one light energy wave and i know it.
