Answer:
velength is the distance between the crests of a wave. Many different things can move like waves, like strings, water, the air (sound waves), the ground (earthquakes), and light can be treated as a wave. Wavelength is represented with the Greek letter lambda: λ. It is equal to the velocity of the wave, divided by the frequency. Wavelength is expressed in units of meters (m).
λ = wavelength, the distance between wave crests (m)
v = wave velocity, the speed that waves are moving in a direction (m/s)
f = frequency, the wave crests that go through a point in a certain time (cycles/s or Hz)
