what is a wave
A rythmic disturbance that transfers energy through matter or space
What are the two general types of waves
Mechanical and electromagnetic
what are the types of mechanical waves
Transverse and longitidual
what is a mechanical wave
a type of wave that requires matter to travel through
what are examples of a medium
An earth quake or rope
what is a transverse
A type of mechanical wave that move through mediums at right angles
what is longitudual
a type of mechanical wave when vibration is parallel to the direct motion
what is frequency and its symbol and its unit
The frequency of a wave is a measure of the number of oscilations of the wave per second symbol (f) unit hertzs
what is periodic time
the periodic time of a wave (T) is the time taken forone complete cycle period = 1/f
what is amplitude
maximum displacement from moon position for either side Measured in me
what is wave length
the distance between two points on a wave train
what is the formula for speed
speed = d/t
what is the formula for displacement
d final - d initial
what is the formula for velocity
displacement/time
what is veloctity
The rate at which an object changes position
