Gamma rays are the highest energy electromagnetic waves. Is there a theoretical limit to this? What about the lowest energy limit?

Thank you for the question dealing with is there a limit to the electromagnetic spectrum.

First it might help if you look at one of the many linear scales of the EM spectrum, either on the WEB do a google search or a Physics Text I would suggest Halliday and Resnicks Physics Text , or the ARRL "HAM" radio Handbook. A picture or graphic is great here.

At this point in time we have a spectrum that we both on the math and experimental side show proof. To say at either end of the spectrum we have found the end or limit is hard, concept this is where this energy is depicted but we are still looking and investigating. You have to consider the energy and we strive to look deeper and deeper via high energy physics.....keep posted and follow events at FERMILAB and CERN (the LHC) we are looking further in to these areas.

I hope this helps you explore the far reaches of the electromagnetic spectrum, good luck......
