What are three mediums that waves can travel through?
The matter through which a mechanical wave travels is called the medium (plural, media). There are three types of mechanical waves: transverse, longitudinal, and surface waves. They differ in how particles of the medium move when the energy of the wave passes through.
Do longitudinal waves require a medium?
A longitudinal wave (sound) is always produced perpendicular to a transverse wave (light), and light does not require a medium in order to propagate, so why do so many people say that sound requires a medium to propagate? This wave of squished and stretched spacetime is a longitudinal wave just like sound.
What can longitudinal waves not travel through?
The particles of the medium vibrate about their fixed mean position in a plane perpendicular to the direction of wave propagation. They move more slowly than P-waves and cannot travel through the outer core because they cannot exist in fluids, e.g., air, water, and molten rock (Fig.
What are examples of longitudinal waves?
Examples of longitudinal waves include: sound waves. ultrasound waves. seismic P-waves.
- ripples on the surface of water.
- vibrations in a guitar string.
- a Mexican wave in a sports stadium.
- electromagnetic waves – eg light waves, microwaves, radio waves.
- seismic S-waves.
