Question

Wave pulse on a string shown in figure is moving to the right without changing shape. Consider two particles at positions $x_1=1.5mand{x}_2=2.5m$. Their transverse velocities at the moment shown in figure are along directions.

• A. positive y-axis and positive y-axis, respectively
• B. negative y-axis and positive y-axis, respectively
• C. positive y-axis and negative y-axis, respectively
• D. negative y-axis and negative y-axis, respectively

Answer 1

The correct option is B negative y-axis and positive y-axis, respectively


Dotted shape shows pulse position after a short time interval. Direction of the velocities are decided according to direction of displacements of the particle.
