Which statement is true for electromagnetic and mechanical waves?(1 point)
Responses
Electromagnetic waves require a medium to travel, but mechanical waves do not need a medium.
Electromagnetic waves require a medium to travel, but mechanical waves do not need a medium.
Mechanical waves require a medium to travel through, but electromagnetic waves do not need a medium.
Mechanical waves require a medium to travel through, but electromagnetic waves do not need a medium.
Mechanical waves sometimes travel through a vacuum, and electromagnetic waves sometimes travel through matter.
Mechanical waves sometimes travel through a vacuum, and electromagnetic waves sometimes travel through matter.
Electromagnetic waves travel mainly through matter, and mechanical waves travel only through a vacuum.
