What’s the smallest item ever photographed? An Australian University research team was been able to photograph the shadow of a single atom.
Professor Dave Kielpinski, from Griffith University’s Centre for Quantum Dynamics, said his research team was curious what they could investigate with visible light. “We wanted to investigate how few atoms are required to cast a shadow,” he said, “And we proved it takes just one.”
The breakthrough which allowed the discovery came using an important piece of equipment — a super high-resolution microscope. This allowed the atom to be frozen in time, and for its shadow to become dark enough to be viewed.
