Waves

-Wave

--Transverse wave

---Elements of medium move in a perpendicular direction to wave

--Longitudinal 

---Elements of medium move parallel to direction of wave velocity

-Speed of wave on a string

-Wave speed

--Rate at which the disturbance propagates along the length of the string in the x direction

--Physical string speed 

-Interference of waves

--Constructive interference- when waves meet crest to crest and trough to trough

--Destructive interference- when crest meets trough

-Superposition principle

--When 2+ traveling waves encounter each other while moving through a medium, the resultant wave is found by adding together the displacements of the individual waves point by point

-Reflection of waves

--When a wave pulse reflects from a rigid boundary, the pulse is inverted.

--When boundary free, reflected pulse not inverted
