Knife Edge Diffraction

Knife edge diffraction is a phenomenon that occurs when light diffracts off a screen, causing fringes to appear in certain regions.
This problem can be solved analytically, involving Fresnel sine and cosine integrals.
The intensity distribution beyond the screen reveals interesting oscillations and behavior based on mathematical functions.
Wavelength plays a role in scaling the function along the x-axis, affecting how diffraction patterns appear.
As wavelengths change, the distribution of intensity patterns adjusts, with long wavelengths spreading out more uniformly.
Increasing the distance from the screen impacts how the intensity pattern spreads out, with a slower rate as the distance grows.
Diffraction effects are most significant for long wavelengths, influencing phenomena such as visual acuity and microscope resolution.
Sound waves also exhibit diffraction due to their long wavelengths, allowing them to bend around obstacles.
Although complex, diffraction is a fundamental aspect of physics with applications in various fields like microscopy and ultrasound technology.
