electromagnetic waves, like radio waves, microwaves, light, and x-rays are examples of transverse waves. Longitudinal waves travel through a medium in a direction parallel to the direction of travel of the wave. Mechanical waves such as sound waves, seismic waves created by earthquakes, and explosions are all examples of longitudinal waves.

Q: What are mechanical waves? A: Waves that require a medium in which to travel. A medium is the _ that waves travel through o Mediums can be solid, liquid, or gas Examples of mechanical waves include sound waves, seismic waves, ocean waves, etc Q: Describe two types of mechanical waves.

Chapter 16 Waves and Sound 179 Chapter 16 WAVES AND SOUND PREVIEW A wave is a disturbance which causes a transfer of energy.Mechanical waves need a medium in which to travel, but electromagnetic waves do not. Waves can be transverse or longitudinal, depending on the direction of the vibration of the wave.Sound is a longitudinal

A wave a moving disturbance. (Sound, water waves, etc. make some material substance move as they go by. Electromagnetic waves, such as light or radio waves, make electric and magnetic fields change strength.) Transverse waves: The medium is displaced perpendicular to the direction of propagation. Examples: light, string waves, water waves .
