In order to grow big and strong, plants require the red and blue light that are part of the visible "white" light produced by the sun. Scientists have now developed a plant-boosting film, that ...

Is there a sufficiently reliable way to get an acceptable measure of the actual colour temperature of the the light generated by an LED bulb, using generic hardware and/or software? Maybe there's an ...

The light generated by synchrotron radiation is produced when charged particles are accelerated by an electric field, unlike lasers that generate coherent light using transitions between atomic energy ...
