Hey mate here is your answer》》
The SI units for wavelength (λ), which is essentially just length, is the meter. However, you'll commonly find wavelengths written in nanometers (1 nm = 1e-9 m) or Ångström (1 å = 1e-10 m or 0.1 nm). The SI unit metre is preferred when dealing with equations because those are generally used by them. Ångström and nanometre are generally preferred in literature because they can easily be written without scientific notation and without a lot of leading zeroes.
Hope this answer will help you..《《
