An optical fibre is a thin strand of high-quality glass. Light can be transmitted through it over very large distances. The optical fibre makes use of the 'total internal reflection' of light. When a ...

In addition to our other problems, we must also contend with transmission (with attenuation), reflection, refraction, diffraction, absorption, and scattering. In addition to our other problems, we ...

This video looks at the refraction of light and demonstrates how refraction can make the handle of a Pyrex jug seemingly disappear.
