What are some similarities and differences between mechanical waves and electromagnetic waves?

Similarities: Both types of waves transfer energy without the transfer of matter. They both can exhibit characteristics such as wavelength, frequency, and amplitude. Both types of waves can be reflected, refracted, and diffracted.

Differences: Mechanical waves require a medium (such as air or water) to propagate, while electromagnetic waves can travel through a vacuum. Mechanical waves are typically slower than electromagnetic waves. Mechanical waves involve oscillations of particles in the medium, while electromagnetic waves involve oscillations of electric and magnetic fields.
