The Graph Shows a Wave Traveling to the Right with a Velocity

question 57

Multiple Choice

The graph shows a wave traveling to the right with a velocity of 4 m/s. The equation that best represents the wave is

• A) y(x, t) = 2 sin(\(\pi\)x/4 - \(\pi\)t) m
• B) y(x, t) = 2 sin(16\(\pi\)x - 8\(\pi\)t) m
• C) y(x, t) = 2 sin(\(\pi\)x/4 + \(\pi\)t) m
• D) y(x, t) = 4 sin(\(\pi\)x/4 - \(\pi\)t) m
• E) y(x, t) = 4 sin(16\(\pi\)x - 8\(\pi\)t) m
