110 - Wave Diffraction
In this video Paul Andersen explains how waves will diffract (or bend) around an obstacle or while traveling through and opening. Diffraction will be maximized when the size of the opening or obstacle matches the wavelength.

What is Diffraction of Light
Diffraction is the bending of light as it passes the edge of an object. An example of this property is the shadow. If observed carefully, the edges of shadows are not solid, but slightly fuzzy.
So, what is going on? Diffraction can be easily explained with Huygens' Principle. Just as the front of a wave passes the edge of an object, the wavelets will cause the succeeding front to bend around the edge.
For some time, it was believed that the bending of light was not due to light itself, but the edge of the object. Not until the British Physicist, Thomas Young, conducted the double slit experiment before light was accepted as a wave.
In his experiment, he made two slits on a barrier and allowed monochromatic light (light of a single wavelength) to pass through. The result is a series of light and dark areas on the screen that could not be explained under the particle model of light. Under the wave model of light, these light and dark areas can be explained with constructive and destructive interference of waves.

Diffraction
Diffraction refers to various phenomena which occur when a wave encounters an obstacle or a slit. It is defined as the bending of light around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle. In classical physics, the diffraction phenomenon is described as the interference of waves according to the Huygens–Fresnel principle. These characteristic behaviors are exhibited when a wave encounters an obstacle or a slit that is comparable in size to its wavelength. Similar effects occur when a light wave travels through a medium with a varying refractive index, or when a sound wave travels through a medium with varying acoustic impedance. Diffraction occurs with all waves, including sound waves, water waves, and electromagnetic waves such as visible light, X-rays and radio waves.
Since physical objects have wave-like properties (at the atomic level), diffraction also occurs with matter and can be studied according to the principles of quantum mechanics. Italian scientist Francesco Maria Grimaldi coined the word "diffraction" and was the first to record accurate observations of the phenomenon in 1660.

What is Diffraction of Light
Diffraction is the bending of light as it passes the edge of an object. An example of this property is the shadow. If observed carefully, the edges of shadows are not solid, but slightly fuzzy.
So, what is going on? Diffraction can be easily explained with Huygens' Principle. Just as the front of a wave passes the edge of an object, the wavelets will cause the succeeding front to bend around the edge.
For some time, it was believed that the bending of light was not due to light itself, but the edge of the object. Not until the British Physicist, Thomas Young, conducted the double slit experiment before light was accepted as a wave.
In his experiment, he made two slits on a barrier and allowed monochromatic light (light of a single wavelength) to pass through. The result is a series of light and dark areas on the screen that could not be explained under the particle model of light. Under the wave model of light, these light and dark areas can be explained with constructive and destructive interference of waves.
