'Laser' is an acronym for 'light amplification by the stimulation emission of radiation'. Its theoretical basis was postulated by Albert Einstein. The first tooth exposed to laser light was in 1960.

Fundamentally, a microscope comprises two subsystems: an illumination system to illuminate the sample and an imaging system that produces a magnified image of the light that has interacted with the ...

Light corn syrup is used to rotate the plane of polarized light on the stage of an overhead projector. A polarizing filter allows only those photons with electric fields oscillating in a single plane ...

Introduction You may have heard that light consists of particles called photons. How could something as simple as light be made of particles? Physicists describe light as both a particle and a wave.

That villain is none other than Arthur Light, better known by his codename, Doctor Light! When Doctor Light first appears in the episode, we find the villain (played by Michael Mosley) sitting in his ...

Light microscopy is used to make small structures and samples visible by providing a magnified image of how they interact with visible light, e.g., their absorption, reflection and scattering. This is ...
