Answer:
y(x, t) = A Sin(ωt ± kx)
Explanation:
Waves can be classifies as either stationary (standing), or progressive (travelling). A progressive wave is one the is a traveling wave, transferring energy along its path. While a stationary wave seems not to be moving.
The general equation for a progressive wave is;
y(x, t) = A Sin(ωt ± kx)
Where: A is its amplitude, t is the time, k is the wave number.
When the wave travels in the positive x-axis direction, the equation changes to;
y(x, t) = A Sin(ωt - kx)
When it travels in the negative x- axis direction, the equation becomes;
y(x, t) = A Sin(ωt + kx)
NB: ω = 2f and k = 2
