Wave speed
Frequency . Wavelength
Frequency=
1/T
Transverse waves propagate
Up and down
Longitudinal waves propogate
To and fro
At what do transverse waves occur to their direction
At right angles
What are longitudinal waves to the direction
Parallel
Define amplitude
Max displacement from the equilibrium position
Define progressive waves
Waves that propagate/are in motion
Define stationary waves
Positions of peaks and troughs aren’t moving/are stationary
An example of a stationary wave
Plucking guitar strings
What is the amplitude at a node
Zero
What is the amplitude at an antinode
Maximum
Define superposition
When 2+ waves meet and their total displacement at any point is the sum of the displacements that each individual wave would cause at that point
What are waves that oscillate one wavelength apart
In phase
