Mother nature did not endow ur spaceship witth the gift of absolute rest, so yes, relative to the ships frame you will go 0 mph after jumping out of it.
The distance from u 2 the mirror gets lorentz contracted according to gamma, which is the lorentz factor l=√l-v^2/c^2.
D=r x t, so t which is time to see ur reflection is (d-gamma/300k)•2
Alright, I figured out the lens array issue.
The lenses aren't used to focus loght at all; theyre used because the silicon coating would be too thin (1 micron) to carry charges. Thus, the array is added.
But if you're using the solar cell on your mobile device which is always moving around (as is the sun), then the focused sunlight would always move out of the active silicon area.
Plus, since polycrystalline is so cheap nowadays, are u sure the cost of adding lenses+the poor optical...
Didnt einstein show that the work function depends on frequency not intensity? If so, than why does the Wysips cell use a magnifying array?
Sorry i don't have a pic, but a diagram of the solar cell may be found using google images.
