Question

5.15 The resolving power of a grating, having N number of total rulings, in the nth order is
(a) nN
(b) n/N
(c) n+N
(d) none of these​

Answer 1

Option A:- nN

This is the correct answer. hope it helps you. Plz mark me as Brainliest

Answer 2

Answer:

The correct option is a).

Explanation:

• The formula for a grating's resolving power is given by: / = nN
• As a result, it varies according to the sequence of the spectrum and the number of slots on the grating.
• The grating constant has no bearing on it.
• A diffraction grating is a periodic optical element used in optics that splits light into many beams that move in various directions.
• A type of structural colouring is the colouration that is emerging.
• A diffraction grating is an optical component that separates (disperses) light made up of a variety of wavelengths (such as white light) into its individual wavelength components.
• The most basic kind of grating has a lot of parallel slits that are widely separated from one another.

The resolving power is nN.
