Question

Describe the Fraunhoffer's diffraction at a single slit and for maxima and minima. Explain it graphically.​

Answer 1

Explanation:

This is due to the diffraction of light at slit AB. ... It is observed that, the intensity of central maxima is maximum and intensity of secondary maxima decreases as the distance from the central maxima increases. The width of central maxima is double, than that of secondary maxim.
