the answer to this question is transverse wave
primary waves
Secondary Wave
S Waves
Transverse or Electromagnetic waves.
secondary waves
In a transverse wave the particle displacement is perpendicular to the direction of wave propagation (at right angles). In a longitudinal wave the particle displacement is parallel to the direction of wave propagation.
angles
The particles in a transverse wave are displaced perpendicularly to the direction of the wave motion. For example, water waves are transverse waves. Think of how in the sea, the wave is moving towards the shore, but the water goes up and down. The water molecules are being displaced vertically, but the wave itself is moving horizontally. This is the characteristic motion of a transverse wave. Transverse waves are also able to move through a vacuum. Light, for example, is a transverse wave, and it can move through space, which is a vacuum. (A longitudinal wave, on the other hand, has particles which move in the same direction as the wave, and cannot travel through a vacuum. For example, sound waves.)
S Waves
S-waves which are a form of seismic wave. Seismic waves are a type of mechanical wave known as a shear or transverse wave that travel through the solid Earth (but not the liquid outer core).

S waves cause rocks particles to move from side to side. The rock particles move at the right angles to the direction of the waves. However liquids can not support shear stresses and therefore S waves can not propagate through them.
A secondary wave causes rocks to vibrate at 90 degrees. This earthquake wave can travel through solids but not through liquids, and causes rock particles to vibrate at right angles to the direction of wave travel.
In a transverse wave the particle displacement is perpendicular to the direction of wave propagation (at right angles). In a longitudinal wave the particle displacement is parallel to the direction of wave propagation.
