Paper Wave Activity
Physics IName___________________________Making WavesPurpose: To learn about the relationship between wavelength and frequency of waves, and to practice measuring and calculating key wave quantities such as wavelength, period, frequency and speed.Materials: 2 meter length of butcher paperstopwatchmarkermeter stickcalculator.Roles:Timer _____________________Puller_______________________Wavemaker_________________Procedure:Tear off a sheet of paper large enough to cover the entire table top. Fold the paper in half, lengthwise. You will be drawing waves along each half section of paper.The wavemaker moves the marker up and down in equal time intervals. It is important to establish a steady rhythm and that the wave amplitude is large enough to occupy the width of the lane on the paper. The wavemaker should begin drawing before the paper gets pulled.Next, the Timer says “start” and two things happen: the puller pulls the paper toward himself at a constant velocity and the timer begins timing. During this time, the wavemaker is drawing on the paper and the timer is helping to guide the paper to keep it on the tabletop.Before the wavemaker reaches the end of the paper, the timer says “stop” and… the wavemaker stops drawingthe timer stops timing. Note the time below in question #4.Follow this procedure for a high frequency and a low frequency case. Each wave should contain at least 3 whole waves. Sketch these in the space below.Use a meter stick and calculator to complete the rest of this activity. Discard waves in an appropriate manner when finished!Wave Sketches: Sketch both high- and low-frequency waves in the spaces below. These must be neat. Draw a line for the equilibrium position through the middle of your wave. Label a wavelength () in each wave. Also, label a crest, a trough and an amplitude.0148590Conceptual QuestionWhat type of proportionality exists between wavelength and frequency? How can you tell from your sketches?Data Wave. Answer the following questions for each of your waves.Measure the wave amplitude in 4 places and find the average. Show this on your sketch.HIGH FREQUENCY:LOW FREQUENCY:What is the length of your entire drawing?HIGH FREQUENCY:LOW FREQUENCY:How much time passed while making the sketch for each wave?HIGH FREQUENCY:LOW FREQUENCY:Using the information from #3 and #4, calculate the speed of the waves. Show all work! (Remember that speed = distance/time)HIGH FREQUENCY:LOW FREQUENCY:Next, measure 3 different wavelengths and calculate an average wavelength for each wave.HIGH FREQUENCY:LOW FREQUENCY:How many waves were produced in your sketch? Note: this may not be a nice, whole number! HIGH FREQUENCY:LOW FREQUENCY:Use your answers from #4 and #7 to calculate the frequency and period of the waves. Show your work. (frequency = waves/sec, period is 1/frequency)HIGH FREQUENCY:LOW FREQUENCY:HIGH FREQUENCYLOW FREQUENCYFREQUENCYPERIODSPEEDWAVELENGTH ................
