The distance from one crest to the next or from one dip to the next may be used to calculate the wavelength.
In actuality, the distance between a wave's point and its equivalent point in the following cycle may be used to calculate a wave's wavelength.
The equation I = I sin t, where I is the current at time t and I is the maximum current, can be used to describe a sinusoidal alternating current.
For a sinusoidal alternating voltage, we may express it similarly by writing v = V sin t, where v is the voltage at time t and V is the maximum value.
The separation between peaks in a sine wave is known as the wavelength.
