- AThe angular width of the central maximum of the diffraction pattern will increase.
- BThe angular width of the central maximum of the diffraction pattern will decrease.
- CThe angular width of the central maximum of the diffraction pattern will remain unchanged.
- DThe diffraction pattern will not be observed on the screen in the case of electrons.
