Electromagnetic waves travel slower than mechanical waves.
Electromagnetic waves travel slower than mechanical waves.

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, can propagate through a vacuum, while mechanical waves, such as sound waves, need a medium (like air, water, or solid materials) to travel through.
