Waves and Electromagnetic Spectrum Review

What is the primary difference in energy transfer between mechanical waves and electromagnetic waves?

• Mechanical waves transfer energy through a field, while electromagnetic waves transfer through matter.

• Mechanical waves transfer energy through matter, while electromagnetic waves transfer through a field.

• Both transfer energy through a vacuum.

• Both require a medium to transfer energy.
