1. Interference: Diffraction and interference are related phenomena. Interference occurs when two or more waves overlap and interact, resulting in constructive or destructive interference. Diffraction, on the other hand, refers to the scattering of waves or particles as they encounter an obstacle or a difference in refractive index.

2. Scattering: Diffraction is a type of scattering, which occurs when waves or particles are deflected from their original path as they encounter an obstacle or a difference in refractive index.

Diffraction has also been used in art and music, such as in the creation of diffraction patterns in photography and the use of diffraction gratings in music synthesizers.

How to Memorize "diffraction"

1. visualize
   

   - Imagine a wave, such as a light wave or an electron wave, encountering a barrier. The wave bends and spreads out, creating a diffraction pattern.

2. associate
   

   - Associate the word 'diffraction' with the image of a wave bending or spreading out as it encounters an obstacle.

3. mnemonics
   

   - Remember the word 'diffraction' as 'diffusing reflection' or 'deflecting action'.
