Question

How are EM waves and Mechanical waves different? * Check all that apply 5 points EM waves can travel through a vacuum. All EM waves are transverse Mechanical waves must have a medium. All Mechanical waves are longitudinal. Some Mechanical waves are longitudinal.

Answer 1

Particles transfer energy physically from one to the other either horizontally in a longitudinal wave, vertically in a transverse wave, or in circles in a surface wave. Waves can also be electromagnetic, which are always transverse and do not require a medium to propagate, like light waves traveling through space.
