In a single slit diffraction experiment, the width of the slit is made double the original width. How does this affect the size and intensity of the central diffraction band ? |
| Answer» The angular width of central diffraction band `=(2lamda)/(q)alpha(1)/(a),` i.e., when slit width is doubled the width of central band becomes half of the initial value. As intensity of central maximum `alpha a^(2),` if slit width is doubled, the intensity becomes four times. | |
