Diffraction Session 1 (Fraunhofer diffraction at a single slit)
*Define diffraction of light. Why is it not evident in daily life?
*Differentiate between Fresnel and Fraunhofer diffraction.
*Discuss Fraunhofer diffraction at single slit. Obtain the relation for resultant amplitude of wave disturbance arriving at any point P on the screen due to light rays diffracted at an angle θ.
*In Fraunhofer diffraction at single slit, obtain conditions for principal maxima, minima and secondary maxima.
*Write condition of maxima and minima in single slit diffraction.
*Obtain the relation for width of central maximum obtained in single slit diffraction experiment.
*Numericals
