Diffraction 3| Intensity variation in single slit diffraction

In a single slit diffraction pattern intensity and width of fringes are

What is meant by diffraction of light? Show graphically the relative intensity distribution for a single-slit diffraction pattern as a function of sin theta and write the condition for the first secondary minimum of diffraction pattern in terms of path difference .

Draw a graph showing the intensity distribution of fringes due to diffraction at single slit

The first diffraction minima in a single slit diffraction pattern is at theta=30^(@) , for light of wavelength=5000 Å. The width of the slit is
