A wave travelling in the + ve x-direction having displacement along y-direction as 1 m, wavelength 2$$\pi $$ m and frequency of $${1 \over \pi }$$ Hz is represented by

y = sin(10$$\pi $$x $$-$$ 20$$\pi $$t)

y = sin(2$$\pi $$x + 2$$\pi $$t)

y = sin(x $$-$$ 2t)

y $$=$$ sin(2$$\pi $$x $$-$$ 2$$\pi $$t)
