Term
| What are the movements in a longitudinal wave? |
|
Definition
- The movements are backwards and forwards in longitudinal waves.
|
|

|
|
|
Term
| What is the equation for working out the wave speed? |
|
Definition
Wave speed = frequency x wavelength
(metre / second, m/s) (hertz, Hz) (metre, m)
|
|
|
Term
|
Definition
The wavelength of a wave is the distance between a point on one wave and the same point on the next wave.
|
|
|
Term
|
Definition
As waves travel, they set up patterns of disturbance.
The amplitude of a wave is its maximum disturbance from its undisturbed position.
It is the distance between the top and the middle of a wave.

|
Term
|
Definition
The frequency of a wave is the number of waves produced by a source each second.
It is also the number of waves that pass a certain point each second.
