Waves

In physics a wave is a disturbance or oscillation that travels through space and matter, accompanied by a transfer of energy.

Transverse Waves

Longitudinal Waves

In longitudinal waves the displacement of the medium is parallel to the propagation of the wave. A wave in a "slinky" is a good visualization. Sound waves in air are longitudinal waves.

For transverse waves the displacement of the medium is perpendicular to the direction of propagation of the wave. A ripple on a pond and a wave on a string are easily visualized transverse waves.Transverse waves cannot propagate in a gas or a liquid because there is no mechanism for driving motion perpendicular to the propagation of the wave.

Different Types Of Waves

Ocean Waves

Heat Waves

Sound Waves

Seismic Waves

Wave Behaviors

Diffraction

Reflection

Refraction

when waves, whether physical or electromagnetic, bounce from a surface back toward the source. A mirror reflects the image of the observer.

when a wave goes through a small hole and has a flared out geometric shadow of the slit. Diffraction is a characteristic of waves of all types. We can hear around a corner because of the diffraction of sound waves. For instance, if a wall is next to you when you yell, the sound will parallel the wall. The wall may stop, but the voice doesn't; sound will almost turn the corner of the wall. This is diffraction.

Statements you need to know about waves

Sound waves are longitudinal waves, and are also mechanical waves.

Longitudinal waves travel faster in denser substances because the more tightly packed the object, the more easily the particles can hit each other.

By changing the temperature, this changes how fast the particles are moving. At higher temperature, the particles are more far apart (sound is slower). At lower temperature, the particles are more dense (sound is faster). Sound waves differ than most waves because a sound wave has to have a very high amplitude to affect the world physically.

The high the frequency, the higher the pitch of the wave. Vice Versa.

The higher the amplitude, the higher the intensity of the wave

How waves are produced and detected

Waves are produced by vibrations and detected when those waves refract, reflect, or diffract off objects or mediums.
