Grating resolution formula
WebWe know the formula to find out the Angular Resolution is θ = 1.22 * λ / d Substituing the known parameters in the above formula we have the equation as follows θ = 1.22 * 150nm / 20mm Simplifying the equation further we get the value of angular resolution as θ = 0.000524 degrees WebA diffraction grating is made by making many parallel scratches on the surface of a flat piece of transparent material. It is possible to put a large number of scratches per centimeter on the material, e.g., the grating to …
