I think both detectors will have destructive.
Here is why...look at this break down for each mirror:
Mirror 1 (beam splitter): half goes straight on half is refelcted, thus 180 out of phase
Mirror 2: Beam has traveled extra 1/4 of a wavelength compared to straight on beam. It is...
I searched for a topic already about this and i couldn't really see one so here we go.
A teacher of mine showed this problem to me and could not see a solution just as i cannot either.
A single laser beam is sent on a path as in the diagram enclosed as an attachment.
If you look in the...
Yes it does spacetime, the parallel axis theorem seems to be what i required because it appears to allow me to just regard the masses as two cylinders with the axis of rotation through their centres. This allows me to simply add mr^2 to the equation for a cylinder, (i think). That also works...
My problem is trying to calculate the moment of inertia for a rod with two weights on the each end (like the type weightlifters lift) turning in a horizontal plane with a wire fixed to the middle of the rod.
How do you calculate this? I suppose it could be seen as two cylinders, one small...
Thanks James...that was very helpful.
The investigation i am doing now is to do with the factors that affect the time period and damping effects of a torsional pendulum. Recommend any good places for research?
