measurements. Physics AT 4. If a ripple tank isn’t available then the following two from are available. Activities listed on Institute of Physics website Demonstrate a fluid (corn starch) on a speaker cone or 4.1.4.2 Waves are described by their amplitude, wavelength, frequency and period. The amplitude of a wave is the maximum displacement of a point on a wave away from its undisturbed position. The wavelength of a wave is the distance from a on one Define: wavelength amplitude frequency peak trough period. Calculate the wavelength of a wave. Calculate the frequency of a wave the number of waves and the time. 1 Calculate the wavelength of a wave from a labelled diagram of a wave. Calculate the frequency of a wave given the number of waves (possibly from interpreting a diagram) and the time. Calculate the speed of a wave. Rearrange the equation to find any unknown given the other two values. What do waves do? What effect does increasing the amplitude/frequency of a sound wave have? Demonstrate the above using a loudspeaker and signal generator connected to an oscilloscope. Vary the frequency and then the amplitude on the signal
