What is the condition for first minimum in case of diffraction due to single slit?

Two wavelengths of sodium light of 590 nm nd 596 nm are used in turn to study the diffraction taking place at a single slit of aperture 2 xx 10 ^(-6)m .Calculate the separation between the positions of first maxima of the diffraction pattern obtained in the two cases.

Determine the angular separation betwen central maximum and first order maximum of the difraction pattern due to a single slit of width 0.25 mm,when light of wavelength 5,890 overset@A is incident on it normally.

What is diffraction of light?

What is diffraction of light? Discuss Fraunchofer diffraction of light at a sibgle slit with the help of diagram and deduce expression for width of central maxima, secondary maxima and minima, State the factor on whic fringe width depends.
