optical fibre communication
... communication fibres. This means collecting light from one source and transferring that light to the optical fibre. This demands COUPLING light from core to the fibre, in a efficient way. Larger light sources are generally easy to align with fibres, but their lower intensity generally delivers less ...

Measurement of the Wavelength of Light
... Visible light is an electromagnetic wave, and one of the basic phenomena of a wave is interference. When light waves reflect from a grated surface, they interfere forming a pattern of bright and dark spots on a screen. By measuring the angles of constructive interference, the wavelength of the light ...
