Question

Which statement is true about electromagnetic and mechanical waves? (1 point) Responses Electromagnetic waves travel slower than mechanical waves. Electromagnetic waves travel slower than mechanical waves. 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 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 are transverse, but mechanical waves are longitudinal.

Answer 1

The true statement about electromagnetic and mechanical waves is: Electromagnetic waves can travel without a medium, but mechanical waves require a medium to travel.

Electromagnetic waves (such as light, radio waves, etc.) can propagate through a vacuum, while mechanical waves (such as sound waves, water waves, etc.) need a medium (like air, water, or solids) to travel through.
