White light-emitting diodes (LEDs) have tremendous potential for energy-efficient illumination. However, achieving white light emission with a 'colour temperature' that is not too blue is a ...

Lasers are known for the monochromatic nature of their light, so much so that you might never have thought there could be such a thing as a white laser. But in the weird world of physics ...

An RGB LED. By mixing the red, green, and blue colors, this LED can emit white light The first white LEDs weren’t explicitly white LEDs. Instead, red, green, and blue LEDs were packed into a ...

If the brightness of light in a double slit experiment is increased what happens to the fringe spacing (distance between two consecutive maxima or minima)?

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 ...
