    A level physics doubt about a Diffraction grating

    Ok sorry. But this is all the relevant formulas for this. My working I’ll show more. But I have no clue for this so I’m getting a completely wrong answer(not even close to the options).

    A level physics doubt about a Diffraction grating

    Well, I took it as: wavelength= 690x10^-9 m D = 300 x 10^-3 m So I tried substituting in the equation but I didn’t know what angle to take. So yeah that’s where I’m stuck.

    A level physics doubt about a Diffraction grating

    Homework Statement Monochromatic light of wavelength 690nm passes through a diffraction grating with 300 lines per mm, producing a series of maxima on a screen. What is the greatest number of maximas that can be observed? A) 4 B) 5 C) 8 D) 9 Homework Equations n*wavelength = d*sin x The...
