What do slinky waves and seismic waves have in common? a. they both always occur as transverse waves. b. they both always occur as longitudinal waves. c. both are electromagnetic waves. d. both exhibit the same particle-to-particle interaction. e. both are mechanical waves.

E> Both are Mechanical waves

Explanation:

As we know that Slinky waves are transverse in nature and medium particles will move to and fro while wave propagate through the medium.

While Seismic waves are of two type

(i) P waves   (ii) S Waves

these both moves in form of compression and rarefaction and it can travel through the medium.

So here in case of Seismic wave we can say it is longitudinal waves.

So here we can say that they both have common that they both requires medium to move from one end to other end.

So they both are mechanical waves
