How to pronounce“diffraction”in English

Diffraction is one of the reasons there's a bright spot in the middle of the shadow when you shine a light on a round object.

Diffraction will happen when light passes through a single slit, too, producing a pattern that looks like a series of lines that get dimmer the farther you get from the center.

Diffraction makes the light waves curve around the coin’s edges.

But diffraction can play a significant role in shadows, and in fact, it was the cause of a massive debate, about 200 years ago...

This diffraction, which is the reshaping of light by obstacles, happens in lenses too.

Exactly how this diffraction pattern looks, depends on the spacing of the slits and the light's wavelength.

We also explored the diffraction pattern from a single slit.
