that travels in the positive direction on a taut string. Which of the following
expressions represents this wave (x and y are in meters and t is in seconds)?
y (cm)
10 cm
t 0s
5 ст
x (m)

-10 cm
O y(xt) = 0.05 sin(2nx- 20nt)/where x and y are in meters and t is in sec.
O y(x,t) = 0.1 sin(2rtx - 20rtt)/where x and y are in meters and t is in sec.
O y(x,t) = 0.05 sin(4rtx + 10rtt)/where x and y are in meters and t is in sec.
%3D
O y(x,t) = 0.1 sin(2nx + 20nt)/where x and y are in meters and t is in sec.
O y(x,t) 0.1 sin(4rtx + 1Ott) /where x and y are in meters and t is in sec.
