| wave | transfer of energy in form of disturbance through a medium |
| frequency | number of cycles per second |
| hertz | unit used to measure frequency |
| period | time required for one cycle |
| amplitude | distance from rest position to maximum displacement |
| pulse | single disturbance |
| transverse wave | partivles in medium vibrate at right angles to direction wave is traveling |
| longitudinal wave | particles vibrate paralle to direction of motion of wave |
| wavelength | midpoint of trough to trough, crest to crest |
| wave equation | v=f(wavelngth) |
| fixed end | inverted reflection |
| free end | regular reflection |
| partial reflection | at boundary between two mediums some reflection occurs |
