1. The displacement of the medium is perpendicular to the direction of wave propagation. This is the defining characteristic of transverse waves. Imagine shaking a rope up and down – the wave travels horizontally along the rope, but the rope itself moves vertically.

2. Transverse waves can be polarized. This means that the direction of the displacement can be restricted to a specific plane. For example, light waves are transverse and can be polarized using filters, which allow only light waves oscillating in a certain plane to pass through.

3. Transverse waves require a medium to propagate. This is because the wave relies on the movement of particles in the medium to transmit energy. Examples of transverse waves that travel through a medium include waves on a string, water waves, and seismic S-waves.
