Your answer
How does a Pulse reflect from a Fixed End? Is the reflection on the same side of equilibrium or the opposite side?
Your answer
How does a Pulse reflect from a Loose End? Is the reflection on the same side of equilibrium or the opposite side?
Your answer
Choose No End. Then click Oscillate. Adjust Damping. What affect does Damping have on the wave?
Your answer
Select Slow Motion and set Damping to None. Use the Timer to time how long it takes one wave crest to move from the source to the window. Now see if the Amplitude affects this time (and thereby the wave speed). Does it?
Your answer
Does the Frequency of the wave affect its speed? Time a single crest as it moves across the screen to find out.
Your answer
Does the Frequency of the wave affect its speed? Time a single crest as it moves across the screen to find out.
Your answer
As the Frequency is increased, what happens to the distance between wave crests (i.e. the wavelength)? What kind of relationship is this?
Your answer
What affect does Tension have on the speed of the wave?
Your answer
Is this a transverse or longitudinal wave?
Study the direction that the particles of the string move in. Notice they are moving up and down, not left or right. If they are not moving rightward, then what exactly is moving rightward? What is moving rightward when a wave is moving rightward?
