electromagnetic vs. mechanical\nspeed\nelectromagnetic mechanical\nthis graph is accurate because \na electromagnetic waves move faster than mechanical waves.\nb mechanical waves move faster than electromagnetic waves.
Answer
Brief Explanations:
Electromagnetic waves travel at the speed of light in a vacuum and generally much faster than mechanical waves which require a medium to propagate. Mechanical waves' speed depends on the properties of the medium they travel through.
Answer:
A. electromagnetic waves move faster than mechanical waves
