In which kind of wave do the particles of the medium move at right angles to the direction in which the wave is traveling. Transverse. In what way do the particles in the wave move when surface waves combine the properties of transverse and longitudinal waves.
In a transverse wave, the particles of the medium move perpendicular to the direction of wave travel. This type of movement can take place in a solid material, in which molecules are tightly bound, but not in a liquid or a gas, in which molecules easily slide past each other.
