Question

fraunhofer diffraction​

Answer 1

Answer:

It is a single slit experiment obtaining for the different types of fringes when light says coming from infinity....

1. Intensity curve always decreases and maximum at the central maxima

2. Gives bad constrast

Answer 2

Answer:

In optics, the Fraunhofer diffraction equation is used to model the diffraction of waves when the diffraction pattern is viewed at a long distance from the diffracting object, and also when it is viewed at the focal plane of an imaging lens.[1][2] In contrast, the diffraction pattern created near the object, in the near field region, is given by the Fresnel diffraction equation.

The equation was named in honor of Joseph von Fraunhofer although he was not actually involved in the development of the theory.
