You calculate that the n = 6 to n = 3 transition in hydrogen will generate a photon with a wavelength of 1090 nm. Will this photon be visible to the eye and what will the energy of this photon be? (RH = 3.29 x 1015 Hz)

This struck me while walking home today. http://i50.tinypic.com/2ni6scm.jpg so this is the general 'representation' of a photon moving forward at the speed of light. Time period t, f = 1/t. However, the photon doesn't move up-down-up-down etc, or else...

my question is what makes a photon to move in a particular direction and does the photon speed or velocity at the time of its birth is same as the speed of light?
Answer:
The long answer is mostly correct. The photon is mass-less so it always moves at the speed of light...
