Duncan Hall Ms. Reine Physics 20 28/05/2018 Standing Waves and the Speed of Sound Background: Using the universal wave equation in a pipe closed at one end, the speed of sound can be derived from manipulating the formula (seen below). If the length of an air column is manipulated while keeping frequency constant, not only can n (harmonic number) can be found, but the speed of sound can be then derived from the equation. Hypothesis: If the frequency is kept constant, then the speed of sound will be higher than 343m/s because that is the international standard for the speed of sound at sea level, since Calgary is much higher than sea level so the atmosphere provides less, but similar resistance.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
