Microscopy

Definition

Microscopy is the science of using microscopes to observe small objects that cannot be seen with the naked eye. It plays a crucial role in analyzing materials at a microscopic level, which is particularly important in fields such as agriculture and soil science where understanding the properties of colloids can affect crop yields and soil health.
