The relationship between energy and wavelength is shown by:
E = hc/wavelength
As we can see, there is an inverse relation between energy and the wavelength. The greater the energy, the shorter the wavelength. Among the mechanical waves listed, at the wavelength of 7 cm.

Cohesive and adhesive forces.
further, we also have vander waal's forces of attraction
Displcement reaction. metal added to solutions containing metal that is less reactive would have visible reaction while less reactive metal will have no visible reaction. Eg, if copper is added to Mgcl2 andZnCl2, there will be no visible reaction. If Mg is added to CuCl2, blue solution will fade to form colourless solution and a reddish brown ppt of Cu will be formed.
