Interpretation Introduction

**Interpretation:**

A grating is given with the wavelength 400nm, angle of incidence 45° and the angle of reflection 7°. Number of lines per millimeter for grating for first order diffraction is to be determined.

**Concept introduction:**

Calculation of spacing between reflecting surface is done by the following formula

And the number of lines is calculated by-
