The concept applies to any periodic wave where the pattern repeats over space or time. The wavelength equation is v = λ x f, where λ is the wavelength, v is the wave velocity and f is the wave's ...

The wave equation is a very important formula that is often used to help us describe waves in more detail. It should be noted that some particular waves have their own specific speeds. The speed ...

Solve \(\sqrt 3 \cos x + \sin x = \sqrt 2\), for \(0 \le x \le 2\pi\). First of all we need to put \(\sqrt 3 \cos x + \sin x\) into the form \(k\cos (x - \alpha ...
