WebThe grating equation can be written: sinα + sinβ m = -mλ/d where: α is the angle of incidence βm is the angle of diffraction. The angles are positive if they are directed counter clockwise, otherwise negative. m denotes the order number of the diffracted beam. m is an integer number, positive, negative or zero. WebThe general grating equation is usually written as: nλ = d (sin i + sin i’) where n is the order of diffraction, is the diffracted wavelength, d is the grating constant (the distance between successive grooves), i is the angle of incidence measured from the normal and i’ is the angle of diffraction measured from the normal.

WebMay 2, 2024 · Resolving power of grating is defined as the capacity to form separate maxima of two wavelength which are very close to each other. This is measured by λ/dλ where dλ is the smallest difference between two wavelengths an λ is mean wavelength. What do you mean by resolving and dispersive power of grating? Webp = 2.λ, high level grating lobe From the above formula, the following general rule can be obtained : If p < λ /2, then no grating lobe is generated whatever the angle of the main beam. If p > λ, then there is always at least one grating lobe generated whatever the angle of the main beam.
