SUMBIT THIS FILE QUESTION#2.PDF In this question we will explore a physical phenomenon through an experiment The relation between the Length of the pipe L and the frequency it produces Objectives of the experiment: . To find the relationship between the length L of the pipe and the frequency it produces For this experiment we will use a spectrum analyzer. To refresh yourself how to use the spectrum analyzer check the video tutorial hereSome background about the phenomenon to study To start, check the follow short video https:/www.youtube.com/watch?v=MWdKPZcoSCw In the video it is possible to see that there is a relation between the frequency and the length of the pipe. Your task in this question is to explore systematically this relationship Instead of using plastic straws we will be using copper pipes. Here is a movie that shows different copper pipes with different length producing different sounds. Watch the movie so you can have a better understanding of the phenomenon you will explore Blowing copper pipes and the sound they produces movie You can see that the pipes produces different sounds. Note the diameter of the pipes, is the diameter changing during the video? Can you estimate the diameter of the pipes? Now is time to start Define the research question this experiment want to explore (Type here in RED) Define the variables involved in the experiment (Independent, Dependent, Parameters) (Type here in RED) Define your hypothesis (Type here in RED) Procedure of the experiment: Read all the procedure BEFORE starting the experiment1. Activate the application Spectroid - spectrum analyzer you downloaded on your phone, or the application Friture you downloaded in your computer. 2. Prepare a table to collect the data as shown below Diameter of the Pipe Length of the Pipe Frequency (mm (cm (Hz Table 1. Diameter, Length and Frequency of the tested pipes in video Experiment 3. Place the spectrum analyzer microphone close to the speaker of the computer When playing the movie you can hear the sound produced for each pipe. Record the data (diameter of the pipe, Length of the Pipe and the Frequency it produces in the Table 1. 5. Double click in the excel sheet below. It will open a spreadsheet with a table where you can place the values you collected, (Diameter, Length and Frequency) and will produce a graph of the Length vs. Frequency 6. Answer all the questions presented belowDiameter Length Frequency of the Pipe of the Pipe L of the Pipe f (mm) (cm) (HZ) Length vs Frequency 550 500 450 350 300 2502 DQE 150 100 50 2 4 6 a Lengthy [cm] 12 14 16 18 20Data Analysis Describe how the data describes the studied phenomenon and the relations between the variables. Present in a final statement the relation between the independent and dependent variable (Type here) Questions (Answer the questions based on the data collected and the sources you explored. Do not forget to mention your "reliable sources"} Question #1: According to the data collected, is the frequency depending on the Length L of the pipe? Justify your answer using the data collected. (Type here in RED) Question #2: Is there a mathematical relationship between the length of the pipe and the frequency it produces? Justify your answer using the data collected (Type here in RED) Question #3: According to the data collected, is the frequency depending on the Diameter D of the pipe? Justify your answer using the data collected. (Type here in RED) Question #4: How do you think changing the gas in the room will change the results of the experiment? Research to justify your answer. (Type here in RED) Question #5: A resonance tube closed at one end is excited with a sound that has a fundamental frequency of 256.0 Hz. If the speed of sound is 345 m/s, what is the length of the tube? (Type here in RED) Question #6: A resonance tube closed at one end with a length half of the length calculated in Question #5 is excited with certain frequency that resonates in the pipe. If the speed of sound is 345 m/s, what is the frequency playing on the open end of the pipe?(Type here in RED in RED) Conclusions: Write the conclusion of your experiment based on your hypothesis and the data collected (Type here in RED) Review BEFORE submitting your work 1) Remove the watermark Open the concerned document.
