Term | Definition |
---|---|
medium | is the material through which a wave travels. |
wave | is a disturbance that transfers energy from one place to another. |
longitudinal wave | particles move back and forth in the same direction that the wave travels, or parallel to the wave. |
transverse wave | is when particles move perpendicularly to the direction the wave travels. |
mechanical wave | a wave that requires a medium through which to travel. |
electromagnetic wave | is a disturbance in electric and magnetic fields. |
wavelength | distance from any point on a wave to an identical point on the next wave. |
wave period | the time required for one cycle |
frequency | a wave tells how many cycles occur in an amount of time |
hertz | one hertz is equal to one cycle per second. |
wave speed | depends on the properties of the medium |
