Re: Nyet. I would say Kyllä (?)

No. Photons have NO mass. They do have momentum and angular momentum though. E = mc2 won't work here.....

J- If photons have no mass, then what is it that 'vibrates' to give them the frequency?

Try E = h*ƒ = h*c / lambda

J- Interesting, this should work for all electromagnetic wavelenghts of radiation. The question is; what does the result tell me?

h - Planck's constant
ƒ - frequency of light \
c - velocity of light > in a vacuum
lambda - wavelength of light

Thanks; et

Cheers
