Physics - Explanation of diffraction patterns

Explanation of diffraction patterns

The wave model explains this pattern by referring to the interference
[1]of the wavelets from the many point sources in the slit. The particle
model has trouble explaining the pattern.

It can be explained by the idea that each point on the wave can be thought
of as a source of secondary, spherical wavelets which then sum together to
produce the new wavefront. This is known as _Huygens' Principle._
Diffraction [2] occurs as waves pass through a gap because some of the
wavelets can spread away from the initial direction of propagation.
