In a single slit diffraction of light of wavelength lambda by a slit of width e, the size of the central maximum on a screen at a distance b is

In a single slit diffraction of light of wavelength lambda by a slit of width e, the size of the central maximum on a screen at a distance b is

In a single slit diffraction, what is the expression of linear width of the central maximum?

If we observe the single slit Fraunhofer diffraction with wavelength lambda and slit width d, the width of the central maxima is 2theta . On decreasing the slit width for the same lambda
