Start the simulation, and focus on the green dot. How does it move? Note: if you find motion of the dot difficult to see, try adjusting the wave speed v to its lowest value. You could also try making the wavelength $$ larger, or the amplitude A smaller.

up and down along the y$-$axis in a circle $$ left and right, along the x$-$axis to the right, along with the rest of the wave

Try adjusting the speed of the wave v$.$ Compare the motion of the green dot for a low wave speed and for a high wave speed, without changing the wavelength $.$ A higher wave speed results in which of the following?

the time it takes the green dot to make a full oscillation is unchanged the more time it takes the green dot to make one full oscillation $$ the less time it takes the green dot to make one full oscillation
