The width of a narrow slit is a. Establish the condition of formation of first minima of the diffraction fringes, produced by illuminating the slit with a light of wavelength `lambda`.

What are the conditions of formation of maxima and minima of diffraction fringes in Fraunhofer diffraction in a single slit?

In a single slit diffraction, what is the condition for formation of first minimum point?

The width of single slit diffraction fringes varies

The width of single slit diffraction fringes varies

In a single slit diffraction, what is the condition for formation of first secondary maximum?

Find the right condition (s) for Fraunhoffer diffraction due to a single slit.

The angular width of central maximum of a Fraunhofer diffraction fringe formed by a narrow slit is measured. For this, the slit is illuminated by a light of wavelength 6000 Å. When the slit is illuminated by light of another wavelength, it is found that the angular width decreases by 30%. Find the wavelength of the light used in the second case. Now, in the first case, the total set-up of the experiment is immersed in a liquid. It is found that, the angular width of central maximum decreases by same amount. Calculate the refractive index of the liquid.

In Fraundhofer diffraction experiment the first minima of red light (lambda=660mm) is formed on the first maxima of another light of wavelength lambda . Find the value of lambda .

For a parallel beam of monochromatic light of wavelength lambda , diffraction is produced by a single slit whose width a is of the order of the wavelength of the light. If D is the distance of the screen from the slit, the width of the central maxima will be

Instead of violet light if red light is used in the formation of diffraction pattern in a single slit, the diffraction band will be wider- is the statement correct?
