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?

A sine wave is an S-shaped waveform defined by the mathematical function y = sin x. It is depicted graphically as two semi-circular curves that alternate above and below a center line.

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.
