Does the medium in which a wave travels move along with the wave itself.
I think the answer is no, but why?

Except for electromagnetic waves, which do not require a medium, the answer is yes. The medium moves back and forth, and that is what the wave motion is all about.
I thought the medium travels horizontally in a wave. Thanks.
The direction the wave moves depends upon the wave. It moves longitudinally (back and forth in the wave direction) with sound, but up and down (transverse) with seismic waves. Near the surface of water, the medium moves in elliptical loops, both up and down and back and forth.
An electron of mass 9.11 10-31 kg has an initial speed of 2.60 105 m/s. It travels in a straight line, and its speed increases to 7.40 105 m/s in a distance of 5.20 cm. Assume its acceleration is constant.
(a) Determine the magnitude of the force exerted on the electron.

Your response is off by a multiple of ten. N
(b) Compare this force (F) with the weight of the electron (Fg), which we ignored.
