State Huygens' principle. Using this principle draw a diagram to show how a plane wavefront incident at the interface of the two media gets refracted when it propagates from a rarer to a denser medium. Hence, verify Snqll's law of
(i) Using Huygens' construction of secondary wavelets explain how a diffraction pattern is obtained on a screen due to a narrow slit on which a monochromatic beam of light is incident normally.(ii) Show that the angular width of the irst diffraction fringe is half that of the central fringe.(iii) Explain why the maxima at `theta=(n+1/2)lambda/a` become weaker and weaker with increasing

Using Huygens' principle, draw a diagram showing how a plane wave gets refracted, when it is incident on the surface separating a rarer medium from a denser medium. Hence, verify Snell's laws of
