If you were to focus an extremely large area of light of a given frequency into a small area of empty space say from 300,000,000m X 300,000,000m into 1m^2...would you get an increase in frequency?

I understand that the waves may collide and possibly summate...

If the frequency of the light in the smaller area did increase..then given E=MC^2 and E=hν, (C^2 and Planck's constant each being unchanging, thus mass and frequency would be the variables) and if E=E in both equations, then MC^2=hv..., and subsequently M=hv/C^2...thus mass is directly proportionate to frequency...and since frequency can theoretically increase or decrease infinitely, increasing frequency increases mass.

So if the above is possible, it would then be feasible to tune a lens to a specific frequency...which would in turn allow for designing a device perfectly calibrated to take in solar light and emit specific forms of matter.

Hi, OuterGalactic,

Welcome to PF!

The superposition of waves with frequency f is still a wave with frequency f.

Thanks for the welcome Ben

Do you think the frequency would increase if you collided light at a focal point?

No. Maxwell's equations are linear.

So what happens to super-massive amounts of photons when they collide?
