Examine the wavelengths of sine waves 1 and 2. Is there a mathematical relationship between their wavelengths and the complex wave's wavelength? If so, what is that relationship?

Sine wave showing peaks, troughs and wavelength. The amplitude (\ ... The wavelength (\(\lambda\)) of a wave is the distance from any point on one wave to the same point on the next wave along.

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