We had a test a week ago, it asked for Acceleration Potential of an photon to achieve wavelenth of 0.005 picometer.(adsbygoogle = window.adsbygoogle || []).push({});

Not so surprisingly both of our teachers don't have a clue about what it means. While according to their solution we had to find the kinetic energy.

One more query, you have for photon

p=h/[tex]\lambda[/tex]

i know how you get here with Einstein's equation E^2=(pc)^2+m^2c^4

but again when you put p=mv in momentum of photon it gives 0=h/[tex]\lambda[/tex] (since m=0; mv=0) So i would like to understand what would be momentum, because for a photon again to the eistein's equation both terms are indeed (pc)^2 (since p=mc).
