SUMMARY

The discussion centers on the relationship between slit width and wavelength in diffraction phenomena. It is established that the slit width does not have to be strictly on the order of the wavelength for diffraction to occur; it can be significantly smaller or larger. The conversation references the Kirchoff integral theorem as a foundational concept in understanding diffraction. This theorem provides a mathematical framework for analyzing wave propagation and diffraction patterns.

PREREQUISITES
  • Understanding of wave phenomena
  • Familiarity with diffraction concepts
  • Knowledge of the Kirchoff integral theorem

In diffraction why the slit width has to be the order of wavelength of wave? I don't understand. The smaller the width of the slit i think the more effective diffraction becomes.
Why the width has to be order of the wavelength?

It doesn't. It can be much smaller or much larger. Diffraction theory can easily account for both.

Look up "Kirchoff integral theorem".
