Measurement Units in Microscopy

The video tutorial explores the concept of measuring different scales, starting with human hair, which is 100 micrometers wide. It discusses the limits of human eye resolution at 10 micrometers and delves into atomic measurements in picometers. The journey continues to the atomic nucleus, measured in femtometers, highlighting the vast range of scales from human hair to subatomic particles.
