What is meant by the wavelength of a wave?

• the wavelength is the distance between adjacent identical parts of a wave, parallel to the direction of propagation

• the wavelength is the distance between adjacent identical parts of a wave, perpendicular to the direction of propagation

• the wavelength is the distance between a crest and the adjacent trough of a wave, parallel to the direction of propagation

• the wavelength is the distance between a crest and the adjacent trough of a wave, perpendicular to the direction of wave propagation
