Wave Motion

Question 1

Speed of transverse waves in solids

Answer 1

v = (coefficient of viscosity/ density)

Question 2

Speed of transverse wave in stretched string

Answer 2

v = (T/m)^1/2
= (Mg/(||row r^2))^1/2

Where M/l=m

Question 3

Equation of wave

Answer 3

y = Asin(wt +_ kx)

Where
w=2||/T
k=2||/wavelength

Question 4

What is k

Answer 4

It’s angular wave number

Question 5

Phase difference

Answer 5

/\phi = (2||/wavelength)/\x

= (2||/T)/\t

Question 6

Particle velocity =

Answer 6

-slope of wave curve X wave velocity

Question 7

Particle acceleration =

Answer 7

d(particle velocity)/dx

Question 8

Intensity =?

Answer 8

Power/area of cross section = (1/2) X density X v X A^2w^2

Question 9

v =?

Answer 9

w/k
