What is the main difference between mechanical and electrical waves? 1. mechanical waves involve transfer energy and, electromagnetic waves do not 2. mechanical waves require a medium to travel in and, electromagnetic waves do not 3.mechanical wave altitude and wavelength and, electromagnetic waves 4.mechanical waves speed and frequency and, electromagnetic waves

Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission. Electromagnetic waves travel in a vacuum whereas mechanical waves do not
