Expression for resolving power and dispersive power

1.	Expression for resolving power and dispersive power
Answer» Answer: 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.
