2. What is a wave? How are these waves made?. 4 pt 3. What types of waves exist? How are these waves similar and different? Be specific. 4 pt 4. Recall the word "speed". What is speed? What equation(s) do we have for calculating speed? How can we measure the speed of a moving object? 4 pt 5. We often talk about the speed of waves. What do you think we mean when we talk about the "speed" of a wave? 4 pt Go to Wave on a String 1.1.22 Using the simulation, select the fixed end and set AMPLITUDE= 0.50 cm, FREQUENCY=1.5 Hz, DAMPING=none and tension at" Low"6.(Low Tension) -Describe the motion of the individual particle on the string at the very start until a longer time. What happens to the particles at the fixed end? 5 pt Change the tension to "High" 7. (High Tension)-Compare and contrast the behavior of the particle in high tension compared to low tension. 5 pt Using the simulation, select loose ends and set AMPLITUDE= 0.50 cm, FREQUENCY=1.5 Hz, DAMPING= none and tension at a.) Low and a. (Low Tension) 8.Low tension-Describe the motion of the individual particle on the string at the very start until a longer time. What happens to the particles at the loose end? 5 pt b.) ( High Tension ) 9. High Tension -Compare and contrast the behavior of the particle in high tension compared to low tension. 5 ptCONCEPTUAL QUESTIONS: 5pt/each 10.If we increase the frequency to 3.0 Hz and amplitude= 0.75 cm with low tension, describe the number of waves produced?( hint: one wave is equal to a one full cycle) 11. If we increase the frequency to 3.0 Hz and amplitude= 0.75 cm with high tension, describe the number of waves produced? 12. What happens to the wavelength if we decrease the wave speed? Explain the answer . 13.What happens to the wavelength if we increase the frequency? Justify your answer. Speed of wave and tension: Set to "Pulse"; "Fixed End"; Damping = None; Tension = Low.Turn the Ruler and Timer on. Use the ruler to measure the length of the string. You may click and drag the ruler to move the ruler. Record Click the button on the pulse generator to send a pulse through the rope Use the timer to measure how long it takes for the pulse to travel back and forth 5 times. Repeat on moderate and High tension 14.Results: 10 ptString length = (cm) Show work Tension Time for Time to Distance to Speed of wave = pulse to travel travel one distance/ time travel 5 one length(cm) (cm/5) lengths(s) length(s) Low Medium High 15.Conclusion: How does tension affect the speed of a wave in a rope?5 pt Relationship between wavelength and frequency Set to "Oscillate" and "No End" Keep the ruler and timer on.Set the frequency to 1 and tension to low. Measure the time it takes for a wave to travel the length of the string and record in the table below. Do the same measurements at Frequency = 2 and 3 Repeat the experiment at moderate and high tension and complete the table below.Tension Frequency Time to Wavelength Speed = Show work (Hz travel the (cm) Length/time length of the (cm/s) string (5) Low 1 Low 2 Low 3 Moderate 1 Moderate 2 Moderate 3 High 1 High 2 High 3 Conclusion: 5pt each 17.If the tension remains constant and the frequency increases, what happens to the wavelength? 18.Is there any pattern in the wavelength and speed columns of the table (speed and Frequency X wavelength)? 19.What is the relationship between frequency, wavelength and speed of a wave
