Chapter 7: Problem 3
The frequency \((f)\) of a wave is defined as the number of wavelengths per second which travel past a given point. a) For a wave traveling at a given speed, \(c\), how does the frequency depend on the wavelength, if at all? b) Provide a mathematical expression showing the relationship between \(f, \lambda\) and \(c\) for a wave. (Hint: consider how you determined answers to CTQ 2ab).

a) The frequency depends on the wavelength inversely, given the speed of the wave is constant. b) The mathematical relationship is given by \(f = \frac{c}{\lambda}\), where \(c\) is the wave speed, \(f\) is the frequency, and \(\lambda\) is the wavelength.
