Question

The wavelength of the wave in the diagram above is given by letter _____ .

Answer 1

1. The wavelength of a wave is simply the length of a complete wave cycle.
2. In other words, the distance between two consecutive crests or two consecutive troughs of a wave is called the wavelength of the wave.
3. The arrows in the diagram below show the wavelength of a wave.

1. In the above diagram, the letter A represents the distance between two consecutive crests.
2. Hence, the wavelength of the wave in the diagram above is given by the letter A.
