Question

The resolving power greting is

Answer 1

Answer:

The resolving power of a grating is a measure of its ability to spatially separate two wavelengths. ... The chromatic resolving power (R) is defined by R = λ/∆λ = nN, where ∆λ is the resolvable wavelength difference, n is the diffraction order, and N is the number of grooves illuminated
