Wave on a string
A sinusoidal wave propagates on a string as shown in the animation.
What is the amplitude of oscillation, wavelength, and period?
What is the direction of the velocity of the piece of string at x=0 m and t=0 s?
What is the direction of the velocity of the piece of string at x=0.125 m and t=0 s?
What is the speed of the wave?
Now, change the function to a Gaussian pulse. (Click on the "Change" link below the animation and use the function already entered there.) Does it make sense to speak of a wavelength or period? What about amplitude? What is the speed of the pulse?
