How do you work out diffraction grating? Here is my question...
A women uses a diffraction grating with 400 ines per millimetre. For the green spectral line, her graph of sin θn against n is a straight line going through the origin with a gradient of 0.222.
Find a value for the wavelength of the green spectral line which is consistent with these values.


You should give your value in nanometres and to three significant figure

Thanks :)
