Groups: Picture #1a) Would you say this is a periodic wave? Support your answer with characteristics.b) How many waves are shown in this sample? .beginning timeending timetime differentiald) What is the frequency of these waves? (Units in Hz)wavelengthd)Explain how you determined the frequency.e) Calculate the wavelength assuming the speed of sound to be 340 m/s. Relate the length of the sound wave to something in the class room. (Units in meters)f) What is the amplitude of these waves? Explain how you determined amplitude.g) What would be different about the graph if the sample were 10 times as long? How would your answers for the questions a-g change? Explain your thinking. Change the sample rate and test your ideas. Copy the graph and label it #1h.
