Wave Motion Flashcards
1
Q
Speed of transverse waves in solids
A
v = (coefficient of viscosity/ density)
2
Q
Speed of transverse wave in stretched string
A
v = (T/m)^1/2
= (Mg/(||row r^2))^1/2
Where M/l=m
3
Q
Equation of wave
A
y = Asin(wt +_ kx)
Where
w=2||/T
k=2||/wavelength
4
Q
What is k
A
It’s angular wave number
5
Q
Phase difference
A
/\phi = (2||/wavelength)/\x
= (2||/T)/\t
6
Q
Particle velocity =
A
-slope of wave curve X wave velocity
7
Q
Particle acceleration =
A
d(particle velocity)/dx
8
Q
Intensity =?
A
Power/area of cross section = (1/2) X density X v X A^2w^2
9
Q
v =?
A
w/k
