What’s The Smallest You Can See?

From Cleo Abram.

How small can you see? And how does tech help us see as small as individual atoms?

The smallest YOU can see with your eyes is roughly ten thousand times smaller than a meter. Things much smaller than that don’t reflect enough light for our eyes to register. So, people invented the optical microscope, which let us see things down to ten millionths of a meter by shining light and using lenses magnify the image. But past that, objects get smaller than the wavelength of visible light. So we need something even smaller to take a picture, like firing beams of electrons and measuring how they get reflected or transmitted.

There’s SO MUCH of the world that we can’t see with our eyes but we can see with technology!
