1.4 A wave traveling along a string is given by y(x, t)=2 \sin (4 \pi t+10 \pi x) where x is the distance along the string in meters and y

is the vertical displacement. Determine: (a) the direction of wavetravel, (b) the reference phase g0, (c) the frequency, (d) the wavelength, and (e) the phase velocity.
