# Higher frequency waves

Can we artificially create extremely high frequency waves in the ( order of 10^60 )? how hard is it to create high frequency waves, and what limits are potential in doing so...

• Why $10^{60}$? Is there something special about the exponent 60? Is this in units of Hz? – Ben Crowell Jan 19 at 15:48

That's probably impossible, since the wavelength is 16 orders of magnitude smaller than the Planck length. From the Planck–Einstein relation, $$E = h\nu$$, a single such photon would have energy equivalent to about 7.4 million tonnes, and its Schwarzschild radius would be about $$10^{-17} m$$, much larger than the wavelength, thus the photon would be a black hole.
