In National 4 Physics examine the properties of waves and use the wave equation, v = f λ, to relate the speed, frequency and wavelength.

The circuit was successfully tested using a 1-kHz sine wave for the input with an amplitude of 4.5 V, and it produced a 1-V amplitude sine-wave output using a 1-V reference for the set point. See ...
