Question

which of the following waves propagate from the focus during an earthquake?
a transverse
b seismic
c electromagnetic
d none of the above

Explanation:

Earthquakes produce waves that travel outward from their focus, which are specifically called seismic waves. Transverse is a type of wave motion that describes one category of seismic waves (S-waves), but it is not the overarching term for all earthquake waves. Electromagnetic waves are unrelated to earthquake propagation.

Answer:

b. Seismic
