Yeah. The heading says it all.

Light doesn't have "little mass," it has zero mass. But photons do carry momentum:

p = \frac h {\lambda}

where p = momentum, h = Planck's Constant, and \lambda = the wavelength of the light. The article you linked to describes momentum only from a classical Newtonian perspective, so doesn't address the OP's question.

To the OP: the momentum of a photon can be transferred into an atom or molecule and thus change that particle's physical momentum. An example is the effect of "radiation pressure" caused by photons from the sun impacting on a space craft, thus affecting its trajectory - engineers have to take this into account when calculating the trajectory of a probe flying to, say, Jupiter.

I understand. Thanks ebaines!
