group of answer choices

both have a crest and a trough.

both move due to particles bumping into each other.

both can move through matter.

both occur as a result of a disturbance.

both are formed by charged particles.

The characteristics shared by both waves are:

Both have a crest and a trough.

Both can move through matter.

Step-by-step explanation:

Both have a crest and a trough.

True as both electromagnetic and mechanical waves have WAVE NATURE.

Both move due to particles bumping into each other.

False, as electromagnetic waves do not require any material medium to travel, so they travel even without particles bumping into each other

Both can move through matter.

TRUE, but electromagnetic waves can travel even without matter.

Both occur as a result of a disturbance.

False, as only  mechanical waves are created as a result of disturbance.

Both are formed by charged particles.

False, because  mechanical waves are not formed as a result of charged particles.
