I always took the greek letter lambda as the scientific label (symbol) for one wavelength of electro-magnetic energy - typically light.

In the optical world, terms like lambda/10 suggest the RMS deviation of a mirrors surface from the ideal shape (most often a parabola) is not greater than 1/10 the wavelength of light. However, this begs the question - which frequency of light - Red or Blue or something in between.

I would think a mirror support could have great affect on the mirror's surface so maybe this is the relationship.
