| A narrow slit is taken and a parallel beam of moving electrons is incident normally on it. At a larger distance from the slit, a fluorescent screen is placed. Which of the following statement is true if the size of the slit is further narrowed? |
The diffraction pattern cannot be observed on the screen The angular width of the central maxima of the diffraction pattern will increase The angular width of the central maxima of the diffraction pattern will decrease The angular width of the central maxima of the diffraction pattern remains the same |
| The angular width of the central maxima of the diffraction pattern will decrease |
| The angular width of the central maxima of the diffraction pattern will decrease. |
