Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

comment Motion on inclined plane
Viham, I appreciate that (as it says in your profile) you're just starting out in physics. But you need to do a bit more research before posting elementary questions here. For example when I Googled for motion on inclined plane at the top of the list was this article that deals with the problem in detail. Have a read through the article and if necessary Google for more articles. If, after all this, there are still aspects of the problem you don't understand then come back to us.

It sounds as if you want the optical equivalent of a demodulator. Is that a fair summary?

comment Need help in identification of formula
It loks a bit like the equation for a de Broglie wavelength, if $\sqrt{2Mk\epsilon}$ can be interpreted as a momentum.

comment Is it time or duration?
@NikosM. If you take a vector pointing in the time direction then duration is just a scalar that gives the length of the vector. I don't understand why you consider it a significant quantity.

comment Is it time or duration?
I think the question is largely meaningless, but I don't see why it should be closed and I've voted to reopen.
