Indeed thanks and sorry! didn't realize that it's dead already. Anyway, I realized that light has no mass, it is just a form of a wave (just a sort of flow of energy). How silly of me. :D
Who the hell just calls the Light has no mass!
There are Photons (particles) in light hence being conserved that light has mass. If it has momentum then it is sure that it has mass hence is mass = 0 then
P= m X v
= 0 X V
= 0 kgm/s ?? wth?
Pst.
Einstein proved E=mc2 by the help...
