Hi everyone,

Molecules move into a vacuum chamber from an oven at constant T. The molecules then pass through a slit. They reach two rotating discs before finally reaching a detector.

Show that a molecule that passes through the first slit will reach the detector if it has speed, u = ωL/θ.

After it passes through the slit, the beam of particles is directed towards 2 discs that are a fixed distance apart (L). They both have a notch in them, the 2nd disc's notch is offset from the 1st by 1/6∏. T is constant, common angular speed is ω & L = 0.262m.

My question is, do I simply say that the most probable speed is equal to u?

√(2KT/m) = u = ωL/θ

Any clues would be appreciated.

Thanks:)
