Types of waves? |
Longitudinal And Transverse |
|
|
An example of a longitudinal wave? |
Sound wave |
|
|
Describe a longitudinal wave |
Sound wave. Particle direction forward. Energy direction forward. They have rarefractions(spread out)and compressions(compressed together). |
|
|
An example of a transverse wave |
A light wave or water wave |
|
|
Describe a transverse wave |
Light wave or Waterwave. Energy direction forward. Particle direction 90 degrees from forward. Troughs the low bit of the wave. Crests the highest bit of wave. Higher the amplitude the more energy. |
|
|
What is period? |
The period is the time to produce one wave. This is measured in seconds. Divide the time of how long the waves take by the amount of waves |
|
|
What is frequency? |
Frequency is the number of waves produced in the unit time. To find the frequency get the number of waves and divide by the time the wave takes to pass the point (F=n/t). You can also find frequency by dividing 1 by the period (F=1/T) or using the V=Fλ formula and rearrange |
|
|
How do you measure wave speed? |
To measure wave speed you can use the V=D/T formula and the V=Fλ formula |
