Problem: What happens to a pattern of diffraction when you:a. Increase the wavelength (for double slit and single slit pattern)?b. Slits are moved apart (for double-slit pattern)?c. Each slit is widened (for single slit pattern)?

Double slit diffraction approximated with:

y_m = mλD/d (d is separation between slits)

Single slit diffraction:

y_m = mλD/d (d is width of slit)

(a) Wavelength increases: y_m  is directly proportional to λ, so...
