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