The path of a photon bends downward just as the path of a thrown baseball does, by the same distance in the same time interval. The distance dropped in each case is $\frac{1}{2}gt^{2}$. In practice, this would be an exceedingly difficult experiment to carry out. Light travels so fast (roughly a foot per nanosecond) that for it to remain in a 1-g field for one second, it would travel about 300,000 kilometers, more than 7 times around the Earth.
