Answer

Brief Explanations:

Mechanical waves need a medium (matter) to travel, like sound waves in air. Electromagnetic waves don't need a medium and can travel through empty space (vacuum), such as light waves. Wavelengths and frequencies vary widely within both types of waves, so those options are incorrect.

Answer:

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