Speed of light captured on new camera

The fastest camera in the world captures images at one trillion exposes per second, making it fast enough to catch the speed of light.

Scientists in America have developed the imaging system dubbed the "ultimate" in slow motion after capturing a beam of light travelling through a one-litre plastic bottle.
The system is based on a streak camera, which uses a narrow slit for an aperture and produces an image of light particles, or photons, passing through the slit.
But creating a video of the speed of light took an hour as the scientists carried out the experiment repeatedly to build up a two-dimensional image.
