**drwls**, Friday, March 26, 2010 at 12:23pm(i) For the frequency f, require that

200*pi*t = 2*pi*f*t

and solve for f. Obviously f = 100 Hz

(ii) For the wavelength L, require that

20 pi (x/17) = 2 pi (x/L).

That means in this case

10/17 = 1/L

L = 1.7 meters.

(iii) The wave speed is f*L = 170 m/s

(iv) The phase difference can differ by added multiples of 2 pi. I assume you want the minimum phase difference.

The difference between 1.1 and 0.25 is 0.85 m. That is 1/2 of a wavelength, so that would be the phase shift.
