?The electromagnetic spectrum?

[raja]

Its more polite question from me that the electromagnetic spectrum
starts from gamma to radio wavelengths.

What after radio?
what before gamma?

Is there some limit?
Any research going on this?

If yes if exists the electromagnetic spectrum beyond the known, will
it be -inf to inf?

If yes, then surely we are in soup in understanding the universe :)

Hey Sasi, long wavelength limit is size of the Universe (size of observable Universe ~ 8.8x10^26 m ) where as lowest limit is the Planck's length (~1.6×10⁻³⁵ m) .

But in principle the electromagnetic spectrum is infinite

why and how Planck's length is lower limit...?

[amit shukla]

could u define a length less then plank scale  ??????/

[Ananta Charan Pradhan]

Hey Chandurie,
This is the lowest measurable length I have heard but I dont know much detail about this. May be either contact  Prof Sivaram or just make a google search to know much about it.
Cheers

If the wavelength is infinite, the frequency is zero, which means time period is infinity ... will it be the limit? and vice versa :(

And once again there is no meaning for the negative wavelength..

for that you need to reach before you arrive........:-)
