Question

Difference between angular dispersive power and the resolving power of a grating

Answer 1

Answer:

Explanation:

Resolving power of grating is the quality of grating element in how clearly it can separate two close waves in the spectrum. Dispersive power of grating is defined by the ratio of change in angle of diffraction to the corresponding change in wavelength. Resolving power = total aperture of the telescope objective x dispersive power. 3.9
