See the Light!Read Now
What we see with our eyes is visible because light bounces of surfaces in the world around us and then interacts with the receptors in our eyes. In this sense we “see” light all the time. But, much in the same way we can stand next to a train track and watch a train speeding by, can we see a beam of light speeding past us? Until recently this was extremely difficult because light travels incredibly fast (186,282 miles per second). In the video below, the folks from Planet Slow Mo, Gavin and Dan, visited the Compressed Ultrafast Photography (CUP) Laboratory at the California Institute of Technology (Caltech) where researchers are able to film events at speeds up to 10 trillion frames per second. By exploiting the scattering of light as it moves through a medium, the researchers are able to film beams of light as they travel! Check the video below.
