What is the minimum wave amplitude amin such that the ant will become momentarily "weightless" at some point as the wave passes underneath it? assume that the mass of the ant is too small to have any effect on the wave propagation. express the minimum wave amplitude in terms of ts, μ, λ, and g?

The lowest wave amplitude Amin in a way that the ant will become weightless for a moment is when the string's achieves a downward acceleration of magnitude g. The minimum wave amplitude in terms of ts, μ, λ, and g is expressed through this formula which is A_min = mu* (lambda/(2*pi))^2*g/T_s
