Question

Go to the Waves on String" simulation on Moodle. Clicking the link will take you to the webpage at the PhET groups's website. Either click Run now" to run the simulation in your browser, or Download" to get the le and run it that way. Play around with it until you are comfortable with the interface. Note that you can pause the simulation and advance time in steps", which you will probably nd useful. Once you are comfortable do the following: set the damping" slider to zero, select the No end" button, press the Manual" button, set the Tension" slider to low", click on Rulers" and Timer" so that you have rulers and a stopwatch available. One end of the string should now be shown with a wrench holding it that you can move by clicking and dragging it. The other end of the string should be shown going out a window. (a) Wiggle the wrench up and back down to its original position, taking about 2 s for the whole wiggle. Let the resulting wave travel a short distance (say 20 or 30 cm) and then pause the simulation. Adjust the tension slider bar to its middle value. Unpause the simulation and wiggle the wrench up and down again taking the same amount of time. You might want to repeat this whole process a few times to make sure that you see what is going on. i. Which wave is longer, the rst one you generated or the second? ii. Compare the speeds. Do the two waves travel at dierent speeds? Has anything noteworthy happened to the speeds? iii. These aren't periodic waves, so we can't dene their periods. But we can talk about the amount of time each takes to pass by any point. Which wave takes longer to pass any point on the string? Explain why each of the above comparisons makes sense in terms of what we know about these wave properties in general. HERE THE LINK http://phet.colorado.edu/en/simulation/wave-on-a-string

Explanation / Answer

1)the second one generated is longer 2)yes the waves travel at different speeds. yes when the both ends are free and when one is fixed both harmonics are differerent 3)the wave near to the fixed end take more time to pass a point because as the distance increases the energy decreases..
