Angular width of the central maximum of a diffraction pattern due to a single slit does not depend upon:

In an experiment,electrons are made to pass through a narrow slit of width $'d'$ comparable to their de-Broglie wavelength. They are detected on a screen at a distance $'D'$ from the slit (see figure). Which of the following graphs can be expected to represent the number of electrons $'N'$ detected as a function of the detector position $'y'$ ($y = 0$ corresponds to the middle of the slit)?

Light of wavelength $550\, nm$ falls normally on a slit of width $22.0 \times 10^{-5}\, cm$. The angular position of the second minima from the central maximum will be (in radians)

Angular width $(\beta)$ of the central maximum of a diffraction pattern on a single slit does not depend upon

In a double slit experiment,the two slits are $1\, mm$ apart and the screen is placed $1\, m$ away. $A$ monochromatic light of wavelength $500\, nm$ is used. What will be the width of each slit for obtaining ten maxima of the double slit pattern within the central maxima of the single slit pattern? .......$mm$

In diffraction,all fringes have .....
