Question 1

Describe how to determine the slit spacing $d$ and the number of lines per millimetre $N$ of an unknown diffraction grating using a monochromatic laser of known wavelength $λ\lambda$ .

As part of your answer, explain how to:

analyse the measurements collected using a graphical method.
improve the accuracy of the measurements taken.

You are given a laser of known wavelength $λ\lambda$ .
