Answer 1

Hey Jessica -- waves have three basic traits ... how big it wiggles -- "amplitude" ...

 

how fast it wiggles -- "frequency" ... how "delayed" it is -- "phase" lag

 

(cosine starts at 1, sine starts at 0 and doesn't reach 1 until 90 degrees later: phase lag of 90deg) ... Regards :)

Answer 2

Hi Jessica;

A wave has crests.  These are the upward displacements of each cycle.

A wave has troughs.  These are the downward displacements of each cycle.

A wave has a line of equilibrium.  This is the line which represents the average of the coordinates between the crests and troughs.
