Wave frequency is a fundamental concept when dealing with sinusoidal waves. Frequency, denoted by the symbol ( f ), refers to the number of cycles a wave completes in one second and is measured in Hertz (Hz). For example, in our exercise, the wave frequency is given as (500 text{ Hz}). This means that every second, the wave completes 500 ...

Sine waves, or sinusoidal waves, are smooth and repetitive oscillations that are very common in physics due to their simple and predictable nature. They represent a pure form of a periodic wave – think of them as the smooth, undulating paths traced out by a point rotating at a constant speed on a circle, when plotted over time.

So far we have only considered a sine wave as it appears at a particular time. All interesting waves move with time. The movement of a sine wave to the right a distance d may be accounted for by replacing x in the above formula by (x - d). If this movement occurs in time (t), then the wave moves at velocity (c = d∕t).
