Available now in Europe, the US, and Canada in a black or white finish, the Philips Hue Play Wall Washer is $219.99 for a ...

The dispersion of white light happens because the angle of refraction of lights of different colours is different while passing through the transparent medium. For example, ...

On a laser I have, 900 mW input electrical power yields almost 50 mW in green light, so about 10% efficient. Not so bad for a laser. Darned good considering it includes a doubler.

Mitigating risk with real-time, sensor-driven plume dispersion modeling Nov. 11, 2022 When hazardous materials are released, it can be an immediate risk to the safety of the public and responders.

The research continues the application of patterned nanosurfaces to the manipulation of light and removal of unwanted wavelength effects, potentially valuable in several applications. Other examples ...

To do this, the team used so-called sign-alternating-dispersion waveguides. The waveguides are designed to control the dispersion of light by alternately widening and narrowing the beam of light.

Learn about the spectrum of colours found in visible light, how to split white light and the primary and secondary colours of light in this guide for KS3 physics students aged 11-14 from BBC Bitesize.
