The Mechanical Waves and Sound chapter of this Prentice Hall Physical Science Companion Course helps students learn the essential physical science lessons of mechanical waves and sound. medium. Mechanical Waves Mechanical waves are disturbances in matter that carry energy from one place to another. As a mechanical wave, sound requires a medium in order to move from its source to a distant location. Electromagnetic waves are created by a fusion of electric and magnetic fields. Sound is a mechanical wave and cannot travel through a vacuum. Waves are responsible for basically every form of communication we use. Khan Academy is a 501(c)(3) nonprofit organization. the lowest point of a wave below the resting point . This can be a solid, liquid, or gas. ; One interesting property here is that unlike mechanical waves, electromagnetic waves do not need a medium to travel. Surface Waves.
