- There are always two directions that are independent of each other that can be used as the direction of wave.
Longitudinal- In a longitudinal wave, the motion of the particles is parallel to the motion of the wave. When a longitudinal waves moves through a medium, the particles of the medium alternately move closer together and farther apart. The "closer together" part is called a compression, and the "farther apart" part is called a rarefaction.
- Longitudinal waves are difficult to visualize because the motion of the particles is in the same direction as the wave. One way of seeing a longitudinal wave is to stretch out a slinky, and push it in and out. This will set up a wave train made of compressions and rarefactions.
How are waves created?
Waves are created by a wiggle or vibration in time or space which may cause the surrounding medium to vibrate, creating waves. Waves are just a transfer of energy. Waves are up and down motion with direction (defined as a wiggle in time and space), vibration is just up and down motion. A medium is a substance by which another substance is carried or transferred. Light and sound are good examples of waves. Light comes from the sun and travels at the speed of light. Light is special because it doesn't need a medium to transfer through. Sound, like radio waves, travel through air (the medium) in longitudinal waves.
The wave theory states that all the particles exhibit both wave as well as particle nature. It is the defining force behind all types of waves, including sound. The nature of sound waves are the very basis for life and civilization on Earth. Without wave theory, life could not exist.

The interference between two sets of concentric waves that share the same frequency.
The interference from two sets of waves originating from a single source, that traveled through a barrier with two slits
The combination of two or more waves, that results in a new wave pattern with a greater amplitude
The combination of two or more waves, that results in a new wave pattern with a lesser amplitude
Originates from two sources
Starts as a spherical wave
- Waves interfere with only each other
Originates from a single source
Starts as a plane wave
- Waves interfere with stationary objects
A change in the direction a wave is traveling after bouncing off a barrier between two kinds of media
Change in the intensity or direction of a wave after passing by an obstruction who's size is about the size of the wavelength.
-The smaller the distance of the diffraction, the greater the deflection.
Law of Reflection-
The angle of reflection is equal to the angle of incidence
