The purpose of us doing this project is to verify that the speed of sound is 340 m/s and to prove to others through evidences. This project will show others that the speed of sound is 340 m/s, which we can easily prove using daily appliances like smart phone, plastic pipe and water container. We will make use of smartphone apps to generate sound waves of various frequencies.

Research questions
Before we started on the experiment, we thought of some essential questions which are:
  1. How do we ensure and give evidence to show that the speed of sound is 340 m/s?
  2. What methods can be used to find the speed of sound?


After coming up with the questions , we did some background research (Yavuz, A., 2015)  on the questions and finally coming up with a hypothesis:
“I hypothesise that the speed of sound is 340 m / s.”
This hypothesis is to question and make sure the speed of sound is 340 m/s.

Finally, we came gathered all the materials and started on the experiment.
