Researchers Record 'Photonic Boom' at 100 Billion Frames Per Second
We've all heard of sonic booms, which occur when the shock waves produced by an object traveling faster than the speed of sound accumulate to produce a giant pressure wave, but what about "photonic" booms? Researchers have just shown that indeed, light exhibits the same effect, and they used a camera that records 100,000,000,000 frames per second to show it.
