Each colour within the visible light spectrum has its own narrow band of wavelength and frequency. When white light passes through a coloured filter, all colours are absorbed except for the colour ...

Waves close wavesVibrations that transfer energy from place to place without the transference of matter. – including light – can be reflected at the boundary between two different materials.

Central to physics are ideas such as energy, mass, particles and waves. Physics attempts to both answer philosophical questions about the nature of the universe and provide solutions to ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only ...
