The speed of light is often referred to as the universe’s speed limit, making it nearly impossible to catch on camera.
But, a high-tech camera created by researchers at the California Institute of Technology has managed to do that where they observed light speed in a video on “Slow Mo Guys” channel.
Researchers at California Institute of Technology have documented what it looks like when light beam travels at 10 trillion frames per second.
Researchers have invited what they called “world’s fastest camera” which made it possible to catch light speed.
The device called “T-Cup” took images at 10 trillion frames per second. In the clip, scholar Peng Wang started out by recording the speed of light at 100 billion frames per second.
At this rate, it takes a beam of light about 2,000 picoseconds to travel the length of an average water bottle. A single picosecond amounts to about one-trillionth of a second.
To see the light as it speeds through the bottle, researchers diluted the water with a small amount of milk. At a speed of 100 billion frames per second, the light is moving a million times faster than a bullet, according to the Slow Mo Guys.
The camera, which is based on a technique called femto-photography, managed to record the beam of light as it travels across a few millimeters of diluted milk, and the whole process takes about 50 picoseconds.
Particles of light are converted into electrons as they pass through a narrow slit, which allows the camera to take images at 10 trillion frames a second.
The technology could have huge implications for future medical and scientific research.
