What is the highest possible frequency in the electromagnetic spectrum?

Question

I think the very last numeral value of pi is zero ;)

Answer 1

Experimentally, it's currently around 10^24 Hz with the most powerful particle accelerators.

Theoretically, the minimum length of an electromagnetic signal is assumed to be equal to the Planck Length (10^-35 m) which translates into a 10^43 Hz if I'm not mistaken.

Answer 2

I think Planck's constant is the limiting factor, since no transition can take place faster than the limit set by this, this must set an upper limit of the frequency of EMR. Though quite what counts as the transition in this case I'm not sure. But I would surmise that that this would be the transition from zero to cycle peak or trough (quarter of a cycle), which would set the limit at 4 times Planck's constant.

Answer 3

Radiowaves have the highest frequency followed by Infrared radiation, visible radiation, untraviolet radiation, x-rays, gamma rays. Radio frequency can go up to 300 GHz. Above 300 GHz, the absorption of electromagnetic radiation by Earth's atmosphere is so great that the atmosphere is effectively opaque to higher frequencies of electromagnetic radiation, until the atmosphere becomes transparent again in the so-called infrared and optical window frequency ranges.

Answer 4

The higher frequency of Gamma rays so far found is 10^24. The quantum energy is 12400 Mev.

If rays of still higher energy is found then the higher value of frequency will increase further.

Answer 5

What is the very last numerical value of Pi , then I will answer your question!

Answer 6

I don't think there is a largest value. The only limiting factor is 'c' (speed of light). Since :
c= (frequency) * (wavelength)
as long as there is a corresponding wavelength the frequency can be as small or as large as you want it to be.

Answer 7

i have always found that that is near to the electro-frequency ultra chart table in the polygon of life
