Wave Speed Flashcards
1
Q
In a mechanical transverse wave, what are the properties that determine the wave speed?
A
tension and linear density
2
Q
The formula for the speed of a wave on a stretched string
A
v = sqrt(T/[m/L])
3
Q
the SI unit for tension
A
Newtons / N
4
Q
the SI unit for linear density (μ)
A
kg/m
5
Q
What does v = sqrt(T/[m/L]) tell us?
A
increasing the tension on the string allows the wave to propagate faster, whilst linear density of the string slows down wave propagation
6
Q
The formula for tension derived from v = sqrt(T/[m/L])
A
T = v^2(m/L)
7
Q
The formula for wave speed with a given tension Force
A
v = sqrt([F*T]/[m/L])
