Answer 2

Answer:

A wavelength is the horizontal distance between the two peaks of the wave. Light is measured by its wavelength (in nanometers). It is usually characterized by the Greek symbol λ. Visible light is usually defined as having wavelengths in the range of 400–700 nanometers (nm) or one billionth of a meter.
