- Anumber of orders of diffraction visible decreases; angle between first and second orders of diffraction decreases
- Bnumber of orders of diffraction visible decreases; angle between first and second orders of diffraction increases
- Cnumber of orders of diffraction visible increases; angle between first and second orders of diffraction decreases
- Dnumber of orders of diffraction visible increases; angle between first and second orders of diffraction increases
