Which statement is true about electromagnetic and mechanical waves? (1 point) Responses Electromagnetic waves can travel without a medium, but mechanical waves require a medium to travel. Electromagnetic waves can travel without a medium, but mechanical waves require a medium to travel. Electromagnetic waves are transverse, but mechanical waves are longitudinal. Electromagnetic waves are transverse, but mechanical waves are longitudinal. Electromagnetic waves all have the same frequency but mechanical waves occur with different frequencies and wavelengths. Electromagnetic waves all have the same frequency but mechanical waves occur with different frequencies and wavelengths. Electromagnetic waves travel slower than mechanical waves.
