what is the difference between a mechanical wave and an electromagnetic wave? a mechanical wave travels through empty space, while an electromagnetic wave travels through matter. a mechanical wave has a short wavelength, while all electromagnetic waves have long wavelengths. a mechanical wave has a high frequency, while all electromagnetic waves have low frequencies. a mechanical wave travels through matter, while an electromagnetic wave travels through empty space.

Answer

Brief Explanations:

Mechanical waves need a medium (matter) to travel, like sound in air. Electromagnetic waves can travel through a vacuum (empty - space), such as light from the sun reaching Earth. Wavelengths and frequencies vary widely within both types of waves and are not defining differences between them.

Answer:

A mechanical wave travels through matter, while an electromagnetic wave travels through empty space.
