Diffraction and Huygens sources

In summary, diffraction is the bending and spreading out of waves as they pass through an opening or around an obstacle. It can occur with all types of waves, including light, sound, and water waves. The Huygens principle helps explain diffraction and its behavior. Single and double slit diffraction are two types, with the latter resulting in an interference pattern. Diffraction is used in various scientific and technological applications, such as in the design of optical instruments and telecommunications.

Hello,

I'm pondering on why bending occurs most when the width of the aperture is close to the wavelength of the propagating wave. According to Huygen's principle, should'nt there be point sources around the edges of an aperture regardless of the width and thus the bending propagate to infinity at even the sharpest angles due to the semicircle of propagation of the point source?

Sorry was there any confusion in my post?
 

1. What is diffraction?

Diffraction is the phenomenon in which waves bend and spread out as they pass through an opening or around an obstacle. This can occur with any type of wave, including light, sound, and water waves.

2. How does diffraction relate to Huygens sources?

Huygens sources are theoretical point sources that emit spherical waves in all directions. Diffraction occurs when these waves encounter an obstacle or opening, causing them to bend and spread out. The Huygens principle helps explain the behavior of diffraction waves.

3. Can diffraction occur with all types of waves?

Yes, diffraction can occur with all types of waves. However, it is most commonly observed with light, sound, and water waves.

4. What is the difference between single and double slit diffraction?

Single slit diffraction occurs when a wave passes through a single narrow opening, causing it to spread out in a pattern of bright and dark fringes. Double slit diffraction occurs when a wave passes through two closely spaced openings, resulting in an interference pattern of bright and dark fringes.

5. How is diffraction used in science and technology?

Diffraction is used in a variety of scientific and technological applications, such as in the design of optical instruments like microscopes and telescopes. It is also used in the study of crystal structures and in the production of holograms. In telecommunications, diffraction is utilized in the design of antennas and in the transmission of radio waves.
