Aku Stress Giler: SLR Lense Tahap Microscope Part II

Moving on with the next part of this jaw dropping pictures...Trust me, you wouldn't believe apa yg korang tengok pasni..

Tapi b4 tu, Me-X nak explain ckit, mcm ner orang ambik gambar macam dlm Part I and Part II ni...FYI, dieorang guna "electron microscope" ...Bawah ni, asal usul benda bernama electron bin microscope, baca sendiri yeee...

"If you looked down the most powerful light microscope in the world, you’d be able to distinguish individual objects that are around 200 nanometres apart – roughly 1/500 the width of a human hair. But objects closer together than that would just merge into one. This is because the wavelength of visible light is longer than 200 nanometres.

But electron microscopes use beams of electrons, instead of light. The wavelength of these electron beams is much shorter, allowing scientists to see structures as small as 1 nanometre (1 millionth of a millimetre).

There are two types of electron microscopes, creating different types of images for different purposes. Transmission electron microscopes (TEM) fire beams of electrons straight through prepared samples of cells, picking up fine details of the tiny structures within. This technique allows scientists to see what’s going on deep within a cell – effectively a “molecule’s eye view”. Scanning electron microscopy (SEM) is slightly different. Instead of firing beams straight through a sample, the beams are angled so they bounce off the cell surface, providing detailed three-dimensional images."

So, faham x? ...haha..kalau malas nak baca, skroll terus ke bawah yo! Jom tengok pictures ni..
