|
|
What are the four characteristics of transverse waves?
|
frequency, amplitude, wavelength, wavespeed.
|
|
|
What is frequency? What is it's symbol? What is the unit of frequency?
|
The number of complete wavelengths that pass a given point in 1 second (symbol ν, nu)
units are (# waves)/seconds or sec^-1, or HERTZ |
|
|
What is amplitude?
|
The height of the wave measured from the origin to its crest or peak
|
|
|
What is wavelength? What is its symbol?
|

|
|
What relationship does wavespeed have with frequency and wavelength?
|
wavespeed (C) = frequency (λ) x wavelength (v)
