hey, i was wondering if this can be possible by human force, if so why are we not finding this?
What is the difference between "one electromagnetic wave" and "another one"? Does a mirror count?
If you want to change the frequency: this is possible with wavelength shifters, acousto-optic modulators, frequency doubling and a few other techiques.
Or simply affect a (large) difference in velocity between yourself and the emitter.
Does gravitational red/blue shifting also counts?
I see that people had trouble with a previous question from you because you tried to translate it from your native language into English:
After you tried again with more words and detail, people could see what you were really asking about. I suggest you try that here also.
actually i mean like, if we can turn radio waves into gamma waves ? sorry for the mistake ive made.
Set up a radio receiver to harvest the energy from radio waves to charge a large battery. Use the large battery to power a gamma ray generator.
