How Does an Electron Microscope Work?
How does an electron microscope work? By using beams of electrons instead of light, it sees things thousands of times smaller than a normal microscope. Here's how.
Instruments & Lab
Microscopes, spectrometers, lasers and detectors — how the tools of science actually work.
How Does a Laser Work? From Atoms to Beam
How does a laser work? Atoms are excited, then release identical photons that amplify in a mirrored cavity to form a coherent, focused beam. Explained step by step.
What Is a Mass Spectrometer? Types & Uses
What is a mass spectrometer? An instrument that weighs molecules by turning them into ions and sorting them by mass-to-charge ratio. Types, how it works, and uses.
