how to measure light wavelength exactly?
does anybody know what the simplest device that can be used to measure monochromatic light wavelength exactly? Thanks.

A diffraction grating (probably the best)
A pair of optical flats with high precision spacers
An optical flat and a precision plano convex lens of known radius to form Newton's rings.
