(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

(a) A thin, taut string tied at both ends and oscillating in its third harmonic has its shape

described by the equation

y(x,t) = 5.60cm (sin[(0.0340 rad/cm)x]sin[(50.0 rad/s)t]),

where the origin is at the left end of the string, the x-axis is along the string and the

y-axis is perpendicular to the string.

(i) Draw a sketch that shows the standing wave pattern. (3 marks)

(ii) Find the amplitude of the two travelling waves that make up this standing wave.

(2 marks)

(iii) What is the length of the string? (2 marks)

(iv) Find the wavelength, frequency, period, and speed of the travelling waves. (4 marks)

(v) Find the maximum transverse speed of a point on the string. (2 marks)

(vi)What would be the equation y(x,t) for this string if it were vibrating in its eighth

harmonic? (3 marks)

2. Relevant equations

3. The attempt at a solution

the only thing i can think to do with this is stick the whole thing in my 89 and do it like that??
