Understanding total internal reflection in physics
Understand the physics behind total internal reflection and why light can become completely trapped inside a medium. This video explains the conditions required for total internal reflection, the role ...
Optical fibres carry light signals at extremely high frequencies, and offer enormous bandwidth for transmitting data. But nonlinear effects may limit their capacity to carry information. Over the past ...
