In the diffraction pattern due to single slit, in the direction of `theta=0` we get

In the diffraction pattern due to a single slit linear width of the central max will be twice that of slit width (d) . The distance between the slit and the screen is

In the diffraction pattern due to a single slit of width 'd' with incident light of wavelength 'lamda', at an angle of diffraction 'theta', the condition for first minimum is

In the diffraction pattern due to a single slit of width 'd' with incident light of wavelength 'lambda' , at an angle of diffraction 'theta' , the condition for first minimum is

In single slit diffraction pattern :

Draw the diffraction pattern due to a single slit by a monochromatic light.

In the case of diffraction pattern due to a single slit angular width of central max can be increased by
