Answer:
Wavelength is a property of waves and it measures the horizontal displacement of a wave.
A transverse wave is a wave that is propagated perpendicular to their source.
The wavelength of a transverse wave measures the distance between two successive crest of the wave.
A longitudinal wave is a wave that is propagated parallel to their source.
The wavelength of a longitudinal wave is the distance between two adjacent compression.
Wavelength is important in determining the velocity of a wave:
Velocity of a wave = frequency x wavelength.
Short wavelength waves have high energy whereas long wavelength waves have low energy
