Physics Tutorial Young s Equation

Note that step ii in the logical proof above demanded that an assumption be made the screen must be very far away compared to the spacing between point P and the central antinodal line That is, L gt gt >y This is an assumption that underlies Young s derivation of his wavelength equation The equation is only as valid as this assumption ,...

Asymptotic stability of oscillations of two

We prove asymptotic stability of periodic oscillations in two-bodies vibrating screen model under assumption that the frequencies w1 and w2 of the generating system without obstacle and periodic driving satisfy the assumption w1 w2=1 2 We also assume that the frequency of the external periodic driving equals to w1 These settings correspond to nonlinear resonance which is a well known ....
