A micrometer is connected to the movable mirror of an interferometer. When the micrometer bears on a thin metal foil, the net number of bright fringes that move, compared to the empty micrometer, is 268. What is the thickness of the foil - in microns? The wave length of light used is 596 nm.

The answer is 79.9 microns, I wonder how to get this result

Answer as many questions as you know. Please give correct explanations.
Q.1 A ladder is resting with one end on a vertical wall & the other on a horizontal floor. Is it more likely to slip near the bottom or near the top?

Q.2 A hollow sphere, a solid sphere, a disc & a ring all having same mass & same radus roll down an inclined plane. If no slipping takes place, which one will take the smallest time to cover a given length?

Q.3 A helicopter flies off, its propellers rotating. Why doesn't the body of the helicopter rotate in the opposite direction?

Q.4 When the angular speed of an object increases, its angular momentum may or may not increase. Give an example of each.

Buddhism teaches the doctorine of impermanence - that suffering is caused by a failure to recognise the impermanent nature of reality, grasping at permanence while it is an impossibility. So from a physics point of view, is anything actually permanent?

I would have thought that left, right, top, bottom were all of the same type ie they all define position maybe ultimately in relation to the human body.
If they are the same kind of thing why should 'left and right' be swapped in a mirror but not 'top and bottom'. One can see why by drawing imaginary lines from the body to it's image but this means that top and bottom and left and right cannot be the same kind of thing. So how could the difference be defined.
