What is mean by the net displacement in transverse wave

In a transverse wave, the particles are disturbed in a direction perpendicular to the direction of wave propagation. Thus, waves travel through a medium with no net displacement of the distance between two successive particles of wave that are in wavelength. 

A hobo is a migrant worker or homeless vagrant, especially one who is impoverished. The term originated in the Western —probably Northwestern — United States around 1890. Unlike a " tramp ", who works only when forced to, and a " bum ", who does not work at all, a "hobo" is a traveling worker.
