Question

Need ans to this question on Wave maths,so that i can compare your solutions to mine.
Transverse waves on a string have a speed of 8.10 m/s, amplitude 7.10 cm and wavelength of 0.320 m.D waves travel in neg x-direction, and at t = 0 the x=0 end of the string has its maximum upward displacement.
a)Find the frequency, period and wave number of these waves.
b)Give a wave function describing these waves.
c)Find the transverse displacement of a particle at x=0.35m at time t=0.15s.
d)How much time must elapse from the instant in part(c)until d particle at x=0.35m has its next max upward displacementNssemes on a string have a speed of 8.10 m/s, amplitude 7.10 cm and wavelength of 0.320 m.D waves travel in neg x-direction, and at t = 0 the x=0 end of the string has its maximum upward displacement.

Answer 1

freequency=25.31 hz (f=vel/wavelength ) time period=0.04s (1/f) wave no=1/lambda =3.125
w=2*pi*25.31 k=pi/0.16
so, -0.071sin(kx-wt)
c) replace values of x and t
d) later...
