  • Core Practical Length vs Frequency

    A fixed load of 400g gives a fixed tension in the 22swg constantan wire. The length of the bridge is changed and the resulting frequency change measured.

  • Core Practical Speed of Sound (Oscilloscope)

    A level Core Practical 6
    Using a classroom c.r.o. (cathode ray oscilloscope) to measure the speed of sound. This is a tricky experiment and this type of oscilloscope in increasingly rare and there is a better demonstration available using a PicoScope.
    The flashing trace is a problem related to the frequency of the camera and the signal.

  • Core Practical Speed of Sound (PicoScope)

    A level Core Practical 6
    Determine the speed of sound in air using a 2 beam oscilloscope, signal generator, speaker and microphone.

  • Core Practical Tension vs Frequency

    A level Core Practical 7
    Measuring the frequency change as more tension is added to a wire

  • Practical. Using Flemmings Left Hand Rule

    Using Flemmings left Hand Rule and F=Bil to find the strength of a magnetic field
