What do slinky waves and seismic waves have in common

Explanation:

Both slinky waves and seismic waves are mechanical waves. Mechanical waves requires a medium to travel. These are of two types i.e. transverse wave and longitudinal waves.

Slinky wave is transverse in nature. The medium particle move to and fro during wave propagation.

Seismic waves are longitudinal in nature. These waves moves in the form of compression and rarefaction. Seismic waves are of two types i.e. P waves and S waves.

Hence, we have concluded that both waves are mechanical waves.
