Homework Statement


In the equation describing the superposition of the two waves to obtain a standing wave, which term represents the wave propagating to the left?


Homework Equations



Y(x,t) = Asin2[tex]\pi[/tex](t/T - x/[tex]\lambda[/tex]) + Asin2[tex]\pi[/tex](t/T +x/[tex]\lambda[/tex])

The Attempt at a Solution


I think its Asin2[tex]\pi[/tex](t/T +x/[tex]\lambda[/tex]) because I remember in math that the + in the sin wave will shift it towards the left, but I am not sure. FYI:
T= Tension
t= rime
A= amplitude
[tex]\lambda[/tex]= wave length
x=distance

Sounds good to me. Do you know calculus? You can also check the sign of
[tex] v<br /> =<br /> \frac{\frac{\partial{Y}}{\partial{t}}}{\frac{\partial{Y}}{\partial{x}}}[/tex]
