Question details
Please exact answers
Read the web page: Wave speed. To give you some experience with wave pulses, go to the PhET simulation, Wave on a string to perform a few tasks. Set the switches to No end and Pulse. Click on Rulers (in the lower right) and Timer, and set the damping to 0. Move the timer so it is next to the start Eid. button. Your screen should look like that shown at the E L right. (It might be useful to set the sim to Slow Motion to better do your measurements.) 1. Press the green button on the device that generates the pulse. Use the timer to measure the time that is takes to move a certain distance along the ruler. (Say from when the front edge passes 4 to when it reaches 6.) Does the velocity you get from this measurement agree with what you inferred in the last assignment from comparing the time to generate the pulse and its width? 2. The slider that allows you to adjust the tension does not have any scale markings. Move the slider to the marker between Low and High. If this were half the tension when the slider was at High, what would you expect the velocity of the pulse to be? cm/s. 3. Choose some way to measure the speed of the pulse when the tension is at the halfway mark. What did you get? cm/s 4. Does this agree with your calculation? 5. Explain why the pulse is narrower when the tension is less
