Sorry if handwriting is unclear :)
θ= angle of diffraction
m= Order of light
d= distance between slits
λ= wavelength of light
was in a rush so explanation for ii) part1 is this: Since the bigger θ is the bigger Sin(θ) will be, the biggest value of Sin(θ) will give the most distinct separation between the two wavelengths. this is achieved when m is greatest.
